Merge patch series "Remove usage of CMD_BOOTx from SPL code"

Anshul Dalal <anshuld@ti.com> says:

Hi all,

We currently make use of CMD_BOOTI and CMD_BOOTZ in the SPL boot flow in
falcon mode, this isn't correct since all CMD_* configs are only meant
for U-Boot proper and not the SPL.

Therefore this patch set adds new LIB_BOOT[IMZ] configs that allow for
more granular selection of their respective compilation targets.

Additionally, this also allows us to more easily disable support for
raw images from secure falcon mode (SPL_OS_BOOT_SECURE) by doing the
following:

  config LIB_SPL_BOOTI
    ...
    depends on SPL_OS_BOOT && !SPL_OS_BOOT_SECURE
    ...
