support/scripts/gen-bootlin-toolchains: allows armv8-a CPU to use armv7-a toolchains

The ARMV7-A toolchains are capable to compile binaries for ARMv8-A CPU
in AArch32 execution state.

This adds the BR2_ARM_CPU_ARMV8A option in the 'conditions' to allow
ARMV8-A CPU such as Cortex-A53 or Cortex-A72 to use ARMV7-A toolchains.
