Hugo Villeneuve 0cd18fa982 ARM DaVinci: Add common peripherals and modules enable functions.
Taken all the duplicated code for enabling common modules and apply
software workarounds from the board specific code into common
functions. Also added comments explaining the workarounds
(from TI errata documents) and replaced some numerical bit numbers
with more meaningful defines.
