Renesas ARM Based SoC Cleanup for v4.3

* Remove non-multiplatform code from timer
* Remove CONFIG_ARCH_SHMOBILE_MULTI check in setup-rcar-gen2.c
  as it is always true
* Remove legacy (non-multiplatform) support for both sh73a0/kzm9g and
  r8a7740/armadillo800eva
* Move to_rmobile_pd from header to source file where it is used
* Use BIT() macro instead of open coding in r-mobile PM code
* r8a7779: Remove usage of GENPD_FLAG_PM_CLK flag which has no effect
ARM: shmobile: timer: r8a73a4 and r8a7790 are multi-platform only

Since commits e042681894b62d60 ("ARM: shmobile: r8a7790: Remove legacy
code") and 9d07d414d4c33d86 ("ARM: shmobile: r8a73a4: ape6evm: Remove
legacy platform"), the R-Mobile APE6 and R-Car H2 SoCs are supported by
multiplatform kernels only.
Hence we can drop checks for these SoCs in legacy kernel builds.
