ARM: shmobile: r8a7779: Correct TMU clock support again

After discussion on the linux-sh mailing list and reference to the
hardware documentation it appears that 'TMU00', 'TMU01' and 'TMU02'
use a common clock.

The sh_tmu.1 portion of this change resolves a regression introduced in
58079fa7d5 (ARM: shmobile: r8a7779: Correct
TMU clock support) and fixes a regression introduced by that patch. That
patch is queued up for v3.9.
