soc: renesas: rcar-sysc: Remove rcar_sysc_power_{down,up}() helpers

Until commit 7e8a50df26f4e700 ("soc: renesas: rcar-sysc: Drop legacy
handling"), the rcar_sysc_power_{down,up}() helpers were public, as they
were called by the legacy (pre-DT) CPU power management code on R-Car H1
and R-Car Gen2 before.

As they are just one-line wrappers around rcar_sysc_power(), it makes
sense to just remove them.

This also avoids a bool/helper/bool conversion in rcar_sysc_power_cpu(),
where a bool is checked to call one of two helper functions, which
just call rcar_sysc_power() with hardcoded boolean values again.
