[PATCH][RESEND] ARM: mach-shmobile: AG5EVM/Kota2 external Ethernet fix

[Magnus Damm]

From: Magnus Damm <damm@opensource.se>

Keep the ZB clock enabled on sh73a0 to allow the BSC
to access external peripherals hooked up to CS signals.

This is needed to unbreak Ethernet support on sh73a0 boards
such as AG5EVM and Kota2 together with the following patch:

 794d78f drivers: sh: late disabling of clocks V2

Signed-off-by: Magnus Damm <damm@opensource.se>

 Rafael, since this patch is Runtime PM clock related, can you
 please merge this with your other 3.1-rc fixes?

 Without this patch sh73a0-based boards cannot use Ethernet.
