ENGR00142296-2 SRTC: Upgrade driver to kernel version 2.6.38
RTC-DEV ioctl interface changed, which required a definition
of new callback mxc_rtc_alarm_irq_enable in SRTC driver.
Also, added a sync call to mxc_rtc_interrupt after a write to
LP domain register to make sure we wait 3 clock cycles in order
for the write to complete, as required by the hardware.
ENGR00142089-3 MX51/MX53: Upgrade SCC2 and SAHARA drivers to 2.6.38
Starting with 2.6.36, ioctl file operation is removed; therefore,
changed ioctl function to unlocked_ioctl function, which has a
different function prototype and requires local locking mechanism
to prevent more than 1 user from accessing ioctls at the same time.
Modified SCC2 driver to obtain IRQs from resource array.
Modified SAHARA driver to use either MX53 or MX51 base address and
irq definitions since the generic versions are no longer defined
in the machine layer header files.
