If configured to use UART{1,2,3,4,5} such as on the Beaglebone RS232
cape or the am335x_evm daughterboard, enable the required clocks for
the UART in use.

In order to support low power state, you must source kernel system
timers to persistent clock, available across suspend/resume. In case of
AM335x device, the only source we have is, RTC32K, available in
wakeup/always-on domain. Having said that, during validation it has
been observed that, RTC clock need couple of seconds delay to stabilize
the RTC OSC clock; and such a huge delay is not acceptable in kernel
especially during early init and also it will impact quick/fast boot
use-cases.
So, RTC32k OSC enable dependency has been shifted to
SPL/first-bootloader.

Depending on if we have DDR2 or DDR3 on the board we will need to call
ddr_pll_config with a different value. This call can be delayed
slightly to the point where we know which type of memory we have.

We do not need to check for EMIF_GCLK and L3_GCLK being active. This
was a hold-over from bringup and no longer required.

This patch uses the code in omap-common to support gpio modules 1-3
on am33xx based boards.
It adds base address and register definitions, enables clocks to the
modules, and enables building the common gpio code for CONFIG_AM33XX
as well as CONFIG_OMAP
