ARM: OMAP1: Prepare for conversion of OMAP1 clocks to CCF

In preparation for conversion of OMAP1 clocks to common clock framework,
identify arch/arm/mach-omap1 local users of those clocks and update them
to call clk_prepare_enable/clk_disable_unprepare() instead of just
clk_enable/disable(), as required by CCF implementation of clock API.

ARM: omap1: move mach/*.h into mach directory

Most of the header files are no longer referenced from outside
arch/arm/mach-omap1, so move them all to that place directly
and change their users to use the new location.

The exceptions are:

- mach/compress.h is used by the core architecture code
- mach/serial.h is used by mach/compress.h

The mach/memory.h is empty and gets removed in the process,
avoiding the need for CONFIG_NEED_MACH_MEMORY_H.

omap16xx: Removes fixme no longer needed in ocpi_enable()

This removes the FIXME message above ocpi_enable being declared
for proper locking in this function. As of the current kernel
verisons there is no need for locking as only one driver uses
this function currently and therefore there is no need for real
locking requirements.

ARM: OMAP1: OCPI: move to mach-omap1/

Move the OMAP1 OCPI "bus" code to arch/arm/mach-omap1, since it is
only used on OMAP1 devices. In the long term, it probably makes sense
to move the OCPI bus code to somewhere under drivers/.
