New struct omap_globals contains the omap processor specific
module bases. Use omap_globals to set the various base addresses
to make detecting omap chip type simpler.
Also introduce OMAP1_IO_ADDRESS and OMAP2_IO_ADDRESS for future multi-omap
patches.

This patch changes 24xx to use new register access, except for clock
framework. Clock framework register access will get updates in the
next patch.
Note that board-*.c files change GPMC (General Purpose Memory Controller)
access to use gpmc_cs_write_reg() instead of accessing the registers
directly. The code also uses gpmc_fck instead of it's parent clock
core_l3_ck for GPMC clock.
The H4 board file also adds h4_init_flash() function, which specify the
flash start and end addresses.
Also note that sleep.S removes some unused registers addresses.

Since 32k timer code is moving to OMAP1 specific dir, move the
32k-based sched_clock() into common code where it is based on the 32k
sync counter and can be used even when using MPU timer.
While moving, change the ticks-to-nsecs conversion to use the helper
functions provided by clocksource.h.
Also removed the unused ticks_to_usec, leaving only ticks_to_nsec.

This patch syncs omap specific core code with linux-omap.
Most of the changes are needed to fix bitrot caused by
driver updates in linux-omap tree.

It's pointless to include mach-types.h if you're not going to use
anything from it. These references were removed as a result of:
grep -lr 'asm/mach-types\.h' . | xargs grep -L 'machine_is_\|MACH_TYPE_\|MACHINE_START\|machine_type'
