Merge tag 'renesas-soc-cleanup-for-v3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas into next/cleanup

Merge "Renesas ARM Based SoC Cleanup for v3.17" from Simon Horman:

- Use shmobile_init_delay on r8a7790, r7s72100 and EMEV2 SoCs
- Remove unused redundant callbacks on EMEV2 SoC

* tag 'renesas-soc-cleanup-for-v3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas:
  ARM: shmobile: Remove unused r8a7790_init_early()
  ARM: shmobile: Use r8a7790 DT CPU Frequency for Lager
  ARM: shmobile: Use r8a7790 DT CPU Frequency in common case
  ARM: shmobile: Use shmobile_init_delay() on r7s72100
  ARM: shmobile: Use shmobile_init_delay() on Genmai boards
  ARM: shmobile: Update r7s72100 DTS to include CPU frequency
  ARM: shmobile: Get rid of redundant EMEV2 mach callbacks
  ARM: shmobile: Use shmobile_init_delay() on EMEV2
  ARM: shmobile: Update EMEV2 DTS to include CPU frequency
