Subject: [PATCH / HP6XX] : Add Timer values into HD64461.h

Greetings,

Shortlog:
This patch adds HD64461 Timer adresses & registers to the HD64461 header file (/include/asm-sh/hd64461.h).
The timers (TMU0 & TMU1) can hold 16bit values and auto loads the counter constant when it
reaches zero. Upon reaching zero it generates an interrupt.
