[GIT PULL] OMAP: UART cleanup and runtime PM conversion for v3.3

[GIT PULL] OMAP: UART cleanup and runtime PM conversion for v3.3

[Kevin Hilman]

Tony,

Please pull the OMAP UART cleanup and conversion to runtime PM.  I had
to rebase it onto your soc branch due to the serial.c changes there.

This includes changes to drivers/tty/serial/omap-serial.c and those
changes have Acks from Greg KH and Alan Cox and I got the OK from them
to merge this all together via the OMAP tree.

Thanks to Govindraj for his persistence with this series.

Boot tested on 2420/n810, 4430/Blaze, 4430/Panda
Additional PM testing on 3430/n900, 3530/Overo, 3630/Zoom3.

NOTE: while normal UART behavior works fine with this series, including
      suspend/resume, in order for wakeups from runtime PM to work, this
      series depends on the PRCM IRQ chaining series from Tero and the
      the new hwmod init state from Rajendra[1].  However, since runtime
      PM is disabled by default for the UARTs, they will behave normally
      even without those dependencies.

Kevin

Thanks pulling this into uart branch.
