Convert OMAPs 32kHz clocksource implementation to use the generic MMIO
clocksource support. This achieves several things:
1. It means we get rid of all these helper functions which frankly should
never have been necessary.
2. It means omap_readl() inside these helper functions does not appear in
ftrace output.
Another plus is that we avoid the overhead of calculating the address to
read each time, but a minus is that we use readl() which has a barrier.
