Add PSCI "enable-method" DT property to all application CPU cores.
This allows the OS to bring application CPU cores up and down.

i.e. will queue in renesas-devel for v7.3.

NOTE: This depends mainline TFA 2.15 or newer (or SDK TFA version
which includes b950bc09f5e9 ("plat: rcar_gen5: Fix multicore
boot by ensuring fixed address for plat_secondary_reset"))
and on SDK 4.32 or newer SCP firmware.

I assume SDK 4.32 includes a sufficiently new TFA

It does not, but it does include sufficiently patched old TFA.
