Several modules have issues with HS400 at 100MHz at room temperature
but they seem to work fine at HS400 at 200MHz. Do not restrict
frequency for now.
This reverts commit 166fb4842e780f63c31622af706335e7dcd48c24.

During temperature testing modules print the following error every
now and then:
[ 12.231006] mmc0: Timeout waiting for hardware interrupt. retries left=0 opcode=12
Often the SDHC controller/driver does not recover from the issue
which leads to a Kernel panic (e.g. during boot the kernel can not
mount the root fs).
Lowering the frequency to 100MHz proves to be stable and affects
effective bandwith by less than 5%.

This is only an issue for later Colibri iMX7S 256MB V1.1C and Colibri
iMX7D 512MB V1.1D modules which are currently still in Toradex internal
validation & verification.
Currently without an SD card inserted the regulator framework actually
powers the LDO2 off however e.g. the BL_ON pin is also on that same
rail!
Fix this by specifying LDO2 to be always on and use the regular 3.3V
supply from the carrier board as the vmmc-supply.
Specify that carrier board 3.3V supply to be always on as well to avoid
the following misleading message during boot:
[ 2.299654] 3.3V: disabling
One remaining issue is that now in suspend LDO2 is still powered and
even adding the following did not help:
regulator-state-mem {
regulator-off-in-suspend;
};
Further investigation pending.

This reverts commit 82f0f4f012a646a735d6b44de77b7c9d0712c714.
This is only an issue for later Colibri iMX7S 256MB V1.1C and Colibri
iMX7D 512MB V1.1D modules which are currently still in Toradex internal
validation & verification.
As it turns out not using LDO2 anywhere at all in the regular case is a
bad idea leading to the following:
[ 2.317688] LDO2: disabling
Of course display and SD card still worked on the EvalBoard due to back
feeding through some pull-ups however on Viola with just one pull-up
it failed once both display and SD card were active...

The USDHC instance 1 is powered with a separate rail. This
allows to switch voltage of the SD card signals for higher
speed modes such as UHS-I. The reset state of that rail is
enabled and 3.3V.
Revision before Colibri iMX7S V1.1C and iMX7D V1.1D had
that rail connected to +3.3V rail switchable with a PMIC
GPIO which turned out to be not controllable in regular
run mode and to LDO2.
Colibri iMX7S V1.1C and iMX7D V1.1D and later connect it
to the PMIC LDO2 only, which allows to control the voltage
directly.
This change explicitly assigning the PMIC regulator which
allows the SDHC driver code to control the SD card voltage
and hence negotiate higher speeds for SD cards capable of
UHS-I or later. Note that the carrier board device tree
needs to be adjusted too (see comments at the usdhc1 node)
and the carrier board should have no pull-ups populated.

Add a new hoggrp just for GPIO4_IO23 pin at the module level.
Add this new group to pinctrl-0 in iomuxc by default at module
level and overwrite it at Aster carrier board level without the
new hoggrp-6. This is required so this pin is muxed as GPIO at
module level but can be used by SPI driver as chip select for
Aster carrier board on RPi header X20.

The Standard Colibri pin for Client/Host detection USBC_DET
(SODIMM pin 137) is multiplexed on the module with USB_OTG1_VBUS.
The USB_OTG1_VBUS pad seems to be pulled low by default and not
controllable through pinctrl. When the pin is unconnected on the
Carrier board, the pin is at a intermediate voltage level which is
not ideal. Pull-down the pin to make sure that the pin is at a
defined state by default (low, USB host).

The regulator-always-on property on the Ethernet rail prevents Linux
from disabling the rail when Ethernet is shut down (suspend or simply
link down). With this change the regulator framework will disable the
rail when the Ethernet PHY is not used, saving power especially on
carrier board not using Ethernet.

The iMX7 wakeup pin currently has a 47k pullup configured. Thus
one has to pull the pin to 0V to generate the wakeup event. All
other Colibri modules use pull downs and require 3.3V to generate
an event. Also on the Colibri Evaluation Board an external 100kOhm
pulldown is connected, thus the pin is neither at 0V nor 3.3V but
at 2.2V potentially increasing power consumption.
Change logic to use pulldown and require 3.3V to generate wakeup
event.

The pad SAI1_RX_DATA can be used as second chip select for dual-die
NAND. However, with an assembly option the pad is available as GPIO
on SODIMM 169. All current version of Colibri iMX7 modules have the
pad available as GPIO hence mux it as GPIO by default.
