[U-Boot] [PATCH 2/4] warp7: include: configs: Skip low-level init if BOOTM_OPTEE false

Commit c7b3a7ee5351 ("optee: adjust dependencies and default values for
dram") wants to skip low-level init of i.MX7 hardware in the case where
OP-TEE has already run and u-boot is being run as BL33 in normal world.

Currently we check for both #ifdef CONFIG_OPTEE_TZDRAM_SIZE and #ifndef
CONFIG_OPTEE to determine if lowlevel init should be skipped, however, in
order to ensure non-OPTEE users never see OPTEE related defines we cannot
rely on this method.

Fortunately we can use CONFIG_BOOTM_OPTEE for the same purpose.
CONFIG_BOOTM_OPTEE is only relevant if you want u-boot to load OP-TEE not
if u-boot has already been loaded by OP-TEE.
