From: Gururaja Hebbar K R gururajakr@sanyo.co.in

According to ARM Dual-Timer Module (SP804) TRM (ARM DDI0271),
-- Timer Value Register @ TIMER Base + 4 is Read-only.
-- Prescale Value (Bits 3-2 of TIMER Control register)
can only be one of 00,01,10. 11 is undefined.
-- CFG_HZ for Versatile board is set to
#define CFG_HZ		(1000000 / 256)
So Prescale bits is set to indicate
8 Stages of Prescale, Clock divided by 256

The Timer Control Register has one Undefined/Shouldn't Use Bit
So we should do read/modify/write Operation
