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

[Geert Uytterhoeven]

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.

- Rebased to avoid dependencies.

It looks good to me.
