Subject: [PATCH] ARM: shmobile: rcar-gen2: Correct arch timer frequency on
RZ/G1E

According to the datasheet, the frequency of the ARM architecture timer on
RZ/G1E depends on the frequency of the ZS clock, just like on R-Car
E2 and V2H.

Untested due to lack of hardware.

v2:
  - Rebased to avoid dependencies.
