Configure GPIO_PV2 as SD1_CD# according to latest V1.1 HW.
Leave SDMMC3_CLK_LB_OUT muxed as SDMMC3 with output driver enabled aka
not tristated and input driver enabled as well as it features some
magic properties even though the external loopback is disabled and the
internal loopback used as per SDMMC_VENDOR_MISC_CNTRL_0 register's
SDMMC_SPARE1 bits being set to 0xfffd according to the TRM! This pin is
now a not-connect on V1.1 HW in order to avoid any interference.

Few GPIOs are being used as special function pins
and should not be initialized as GPIOs.

Add a note about the non-working apalis_tk1_gpio_inits table caused by
a reservation failure. If it wouldn't be run in SPL without anything
ever getting printed one would see the following:
A: dir_input: error: gpio A1 not reserved
Please note: The current workaround is to configure pull-up/downs in
the apalis_tk1_pingrps table further below.

Implement optional PCIe EvalBoard initialisation which properly reset the PLX
(now Avago) PEX 8605 PCIe switch plus PCIe devices on the Apalis Evaluation
carrier board.
Please note that you will have to enable the second PCIe port in the dts as well
e.g.:

/* I210 Gigabit Ethernet Controller (on-module) */

While at it also get rid of the DECLARE_GLOBAL_DATA_PTR which is probably a
remnant of the Apalis T30 board file where we use it to get the memory size.

Change file and other names resp. strings to apalis-tk1 rather than
apalis_tk1 due to upstream Linux kernel device tree maintainers no
longer allowing any underscores to be used in any such.
