There are two numbering schemes for the RPi revision values; old and new

sense to have absolute/global names for the revision IDs. Get rid of the
names and just use the raw revision/type values to set up the array of
per-revision data.

This change makes most sense when coupled with the next change. However,
it's split out so that the mechanical cut/paste is separate from the
logic changes for easier review and problem bisection.

rockchip: Explicitly set CONFIG_SPL_STACK_R_MALLOC_SIMPLE_LEN

Now that u-boot relocates the malloc area in SPL to SDRAM, with the
malloc area sitting below the SPL_STACK_R_ADDR the
SPL_STACK_R_MALLOC_SIMPLE_LEN needs to be set explicitly for
rockchip as its SPL_STACK_R_ADDR (512kb) is smaller then
STACK_R_MALLOC_SIMPLE_LEN (1Mb).

Using the same value as SYS_MALLOC_F_LEN (8kb) is enough to load u-boot
from SD card.

rockchip: move SYS_MALLOC_SIMPLE to mach-rockchip Kconfig

Commit 1eb0c03c2198a7ec9de456b83dacdc4831b96cbf added
SPL_SYS_MALLOC_SIMPLE Kconfig option and changed the way it is
evaluated.

Thus, the definitions of CONFIG_SYS_MALLOC_SIMPLE in rk3***_common.h
board configs are now incorrect because CONFIG_SPL_BUILD is enabled so
CONFIG_IS_ENABLED(SYS_MALLOC_SIMPLE) will look for SPL_SYS_MALLOC_SIMPLE
instead of SYS_MALLOC_SIMPLE.

This commit fix this enabling SPL_SYS_MALLOC_SIMPLE with the new Kconfig
