This patch sets up an alias for mmc0 to usdhc3.

Before the DM conversion only usdhc3 was enabled and therefore it appeared
as MMC 0 to u-boot. After enabling MMC DM though usdhc3 defaults to MMC 2,
which left unattended would drive changes to existing warp7 bootscripts and
environment variables that rely on mmc 0.

Setup the alias of mmc0 and usdhc3 so that existing warp7 boot code will
work unmodified.

Passover info only for revA.

move get_cpu_rev out of CONFIG_CPU to avoid build failure when using
get_cpu_rev in SPL.
Add a CONFIG_SPL_BUILD for passover usage, no need to execute it again
in normal U-Boot stage. Also if still checking passover info in normal
U-Boot stage, need to make the passover code executed after
arch_cpu_init_dm.
So to make it easy and clean, only execute the code for SPL stage.

At default, u-boot reserves the memory from SP - 4KB to DRAM end for
lmb in arch_lmb_reserve. So lmb won't allocate any memory from it.
But we found the 4K gap for SP is not enough now, because some FDT
updating operations are added in our u-boot before jumping to kernel,
which needs larger stack. This causes the lmb allocated memory is overwritten
by stack.

Fix the issue by implementing the board_lmb_reserve to reserve from
SP - 16KB to memory end for lmb.

The pinctrl supports to set any bit in input register on iMX6 if
the MSB of input value is 0xff. But the driver uses signed int for
input value, so when executing the codes below, it won't meet.
Because this is arithmetic right shift.

    if (input_val >> 24 == 0xff)

Fix the issue by changing the input_val, config_val and mux_mode to u32.
