ARM: mach-shmobile: sh7372 clock fixes 

Fixes for the sh7372 clock framework:
 - remove unused #include <linux/platform_device.h>
 - add sh7372 prefix to user modifiable root clocks
 - put modifiable root clock prototypes in header file
 - fix off-by-one id error on VEU MSTP clocks
 - make arrays static
