[PATCH] ARM: psci: hide ARM_PSCI options when ARCH_IMX7 is disabled

[Ahmad Fatoum]

We only support providing PSCI on a single SoC, the i.MX7. Having the
option in other configuration is thus confusing.

Therefore hide the symbols when not building for the i.MX7. Using PSCI
as consumer is a separate symbol (ARM_PSCI_CLIENT) and should be
unaffected.
