1. clear RDH bit after resuming back from D3, otherwise, the multi function
pins will retain the low power state
2. save/restore essential system registers

The original code incorrectly returns Hz instead of KHz.

Wakeup sources on PXA3 are enabled at two levels. First, the MFP
configuration has to be set to enable which edges a specific pin
will trigger a wakeup. The pin also has to be routed to a functional
unit. Lastly, the functional unit must be enabled as a wakeup source
in the appropriate AD*ER registers (AD2D0ER for standby resume.)
This doesn't fit well with the IRQ wake scheme - we currently do a
best effort conversion from IRQ numbers to functional unit wake enable
bits. For instance, there's several USB client related enable bits but
there's no corresponding IRQs to determine which you'd want. Conversely,
there's a single enable bit covering several functional units.

This patch is to add the third mmc controller support _only_
for pxa310.
On zylonite, the third controller support one slot.

This patch is to add the second mmc controller support for pxa3xx.
It's valid for pxa3[0|1|2]0.
On zylonite, the second controller has no slot.

Only register the MMC, framebuffer, I2C and FICP devices when the
platform supplies the necessary platform data structures for the
devices.
