Mark pinctrl_wdog as u-boot,dm-spl to clean up board code,
The set_wdog_reset() function is not necessary as this is handled by
the imx_watchdog.c driver due to the 'fsl,ext-reset-output' property
being set.

The uart2 and its pinmux are already marked with u-boot,dm-spl but we
need to move the call to preloader_console_init() after spl_early_init()
to avoid a board hang as dm can't be used until after spl_early_init()
due to the uart driver not enabling the uart clock.
Remove the manual config of the UART pinmux now that it is no longer
needed.

for example a GW7400-A matches the dtb name of gw74xx.dtb

The SPL does not update the memory node with the dram size from EEPROM
but instead we can use get_ram_size which does a simple memory test
to determine the available RAM. Update PHYS_SDRAM_SIZE to 4GiB as that
is the max used on the Venice boards.

The Gateworks System Controller thermal protection feature will disable
the board primary power supply if the on-board temperature sensor
reaches 86C. In many cases this could occur before the temperature
critical components such as CPU, DRAM, eMMC, and power supplies have
reached their max temperature.
Remove the forced re-enable of thermal protection so that users can
knowingly disable it.
