Add a new pin group just for GPIO5_IO04 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 new pingroup.
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 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.

[ Upstream commit d8581c7c8be172dac156a19d261f988a72ce596f ]
The board file for imx6sx-sdb overrides cpufreq operating points to use
higher voltages. This is done because the board has a shared rail for
VDD_ARM_IN and VDD_SOC_IN and when using LDO bypass the shared voltage
needs to be a value suitable for both ARM and SOC.
This only applies to LDO bypass mode, a feature not present in upstream.
When LDOs are enabled the effect is to use higher voltages than necessary
for no good reason.
Setting these higher voltages can make some boards fail to boot with ugly
semi-random crashes reminiscent of memory corruption. These failures only
happen on board rev. C, rev. B is reported to still work.

imx6sx-sdb has custom operating points entries because it has one
power supply that drives both VDDARM_IN and VDDSOC_IN.
As per the MX6UL datasheet we have the following minimum voltages for
198 MHz operation (after adding the 25mV margin value):
VDDARM_IN = 0.975 V
VDDSOC_IN = 1.175 V
So use 1.175V for the 198MHz operation.
