This patch adds revision (.rev) to hwmod class to identify different
timer types. In the present implementation it is used to identify
millisecond timers, legacy timers and highlander timers present in
OMAP4. This identification serves following purposes:
(1) select appropriate timers register maps associated with legacy
ip timers and highlander ip timers present on OMAP4.
(2) select millisecond timers to perform specific operations upon
them during _probe()
