Fix the clkdev API support for the ep93xx uart clocks.
The uarts available in the ep93xx have individual clock controls.
The current implementation assumes that the bootloader has enabled
the clocks before the kernel has booted. It also assumes that the
bootloader has set the UARTBAUD bit indicating that the uarts are
running off the 14.7456MHz external crystal.
This fixes both issues. It also allows the uart clocks to be stopped
when there are no users.

This just leaves include/asm-arm/plat-* to deal with.

Remove includes of asm/hardware.h in addition to asm/arch/hardware.h.
Then, since asm/hardware.h only exists to include asm/arch/hardware.h,
update everything to directly include asm/arch/hardware.h and remove
asm/hardware.h.

Convert the AMBA PL010 serial driver to use the clock infrastructure
to allow EP93xx platforms to properly gate the clock to the UARTs.

Patch from Lennert Buytenhek
Add an initial implementation of the clk_* API for the cirrus ep93xx
to the tree. The initial implementation is somewhat minimal, with the
intention of extending it as we go along.
