ARM: Realview/Versatile: remove useless TIMER_RELOAD calculations
Realview/Versatile copied the Integrator timer code, including the
calculations for ensuring that the reload value fits into the 16-bit
counter. However, these platforms have a 32-bit counter which is
clocked at a slower rate.
The result is that the preprocessor conditions are never triggered:
TICKS_PER_uSEC = 1, mSEC_10 = 10000, which is 0x2710 - less than
0x10000.
So, remove the unnecessary complexity, reducing the TIMER_RELOAD
calculation to just:
TICKS_PER_uSEC * mSEC_10
