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.

During code review it was noticed that the clock value for
TMU01 was incorrect and the value for TMU02 was missing.
For reference: As of 3.8-rc6 there are no in-tree consumes of these clocks.

Initial support for the r8a7779 SoC and the Marzen board (V2).
Only SCIF ports and the TMU are supported at this point.
To keep things simple only entity-mapped virt-to-phys mappings
are supported. This forces drivers and other SoC glue code to
make use of ioremap(). We cannot support early serial console
due to virtual address space collisions with the ARM kernel.
