[ARM] Update SA1111 core and related drivers for LDM. 

This cset updates the SA1111 core, PCMCIA, OHCI and keyboard drivers,
allowing them to take advantage of the Linux device manager code;
this implements initial suspend/resume support for the SA1111 in the
core.  Many existing drivers currently rely on the old PM-based
interface for suspend/resume support.
