Converting uart driver to adapt to pm runtime api's.
Code re-org + cleanup.
Moving some functionality from serial.c to omap-serial.c
Changes involves:
================
1.) Cleaning up certain uart calls from sram_idle func.
2.) Removed all types of uart clock handling code from serial.c
3.) Using hwmod_mux api enable wakeup capability for uart pad during
hwmod_idle state i.e., when uart clocks are disabled we can enable
io-pad wakeup capability for uart if mux_data is available for
given uart. Also during during resume from idle call to uart we need
to enable clocks back conditionally and this can be done only when io-pad
wakeup event bit is set for uart_rx pad. So we need a hwmod api
which can probe the uart pad and let us know whether a uart wakeup
happened. So omap_hmwod_pad_wakeup_status api is added to meet this
requirement.
3.) Adapted omap-serial driver to use runtime api's.
4.) Modify serial_init calls to accept certain uart parameters from board file.
5.) using resume_call to enable uart port back untill we have irq_chaining available.
Patch series is based on Kevin's PM Tree / pm-core branch [2.6.39-rc4]

Testing updates:
----------------
3430SDP:
retention, off_mode, system_wide suspend is tested.
(earlyprintk & no_console_suspend checked)
OMAP3630 - Zoom3:
pm-retention checked, off mode for per domain checked.
[uart3/uart4 in per domain on omap3630].
[ZOOM3 tested with uart3 as console uart and pm-ret checked]
OMAP4430-SDP: Boot tested.
OMAP2420/2430SDP: Boot tested.
