Theodore Karatapanis c6f4310331 arch/arm64/imx9: Guard EL3-only features when booting at EL1 
Boards that run the i.MX9 bootloader at EL1 must not touch EL3-only
configuration. Add Kconfig guards so that:

* DDR training (IMX9_DDR_TRAINING)
* FIQ decode support (ARM64_DECODEFIQ)

are selected only when ARCH_ARM64_EXCEPTION_LEVEL == 3.

Code in arm64_chip_boot() is also guarded with ARCH_ARM64_EXCEPTION_LEVEL == 3
