rockchip: rk3566-radxa-cm3-io: Update defconfig

Update defconfig for rk3566-radxa-cm3-io with new defaults. Also add
missing supported mmc modes to sdhci node.

Remove the SPL_ROCKCHIP_BACK_TO_BROM=y option, SPL is expected to load
next stage from a FIT image and then jump to next stage not back to
BootRom.

Add CONFIG_SPL_FIT_SIGNATURE=y to let SPL verify an auto generated hash
of FIT images. This help indicate if there is an issue loading any of
the images to DRAM or SRAM.

Extend SPL_MAX_SIZE to 0x40000, SPL is loaded to 0x0 and TF-A is loaded
to 0x40000, use the space in between as SPL_MAX_SIZE.

Add config option to include useful gpio cmd.

Remove the CONFIG_NET_RANDOM_ETHADDR=y option, ethaddr and eth1addr is
set based on cpuid read from OTP.

Filter out assigned-clock props with CONFIG_OF_SPL_REMOVE_PROPS,
U-Boot proper will read and configure assigned-clock props.

Add CONFIG_SYS_NS16550_MEM32=y to use 32bit access of serial register.
