Add a new OMAP chip identification interface, omap_chip_id.
omap_chip_id is a structure which contains one bit for each OMAP2/3
CPU type, and on 3430, ES level.  For example, the CHIP_IS_OMAP2420
bit is set in omap_chip at boot on an OMAP2420.  On OMAP3430ES2, both
CHIP_IS_OMAP3430 and CHIP_IS_OMAP3430ES2 bits are set.

omap_chip is set in mach-omap2/id.c by _set_omap_chip(). Other
code should use the omap_chip_is() function to test against omap_chip.

Also, clean up id.c by splitting some code out of
omap_check_revision() into its own function, _set_system_rev(); and
converting some debug printk()s into pr_debug().

Second revision.

New struct omap_globals contains the omap processor specific

Also introduce OMAP1_IO_ADDRESS and OMAP2_IO_ADDRESS for future multi-omap

debugfs can provide the infrastructure to trace the dependencies of
clock tree hierarchy quite visibly. This patch enables to keep track
of clock tree hierarchy and expose their attributes under each clock
directry as below:

	omap:~# tree -d -L 2 /debug/clock/omap_32k_fck/
	/debug/clock/omap_32k_fck/
	|-- gpt10_fck
	|-- gpt11_fck
	|-- gpt1_fck

	|   `-- wdt3_fck
	|-- ts_fck
	`-- wkup_32k_fck
	    |-- gpio1_fck
	    `-- wdt2_fck

	14 directories
	omap:~# tree  /debug/clock/omap_32k_fck/gpt10_fck/
	/debug/clock/omap_32k_fck/gpt10_fck/
	|-- flags
	|-- rate
	`-- usecount

	0 directories, 3 files

Although, compared with David Brownell's small patch, this may look
bit overkilling, I expect that this debugfs can deal with other PRCM
complexities at the same time. For example, powerdomain dependencies
can be expressed by using symbolic links of these clocks if
powerdomain supports dubgfs as well.

This patch optimizes the timer load and start sequence.  By combining the

execution path.

This patch adds the use of write posting for the timer.  Previously, every
write could lock the requestor for almost 3x32KHz cycles.  This patch only
synchronizes before writes and reads instead of after them and it does
it on per register basis.  Doing it this way there is some chance to hide
some of the sync latency.  It also removes some needless reads when
non-posted mode is there.  With out this fix the read/writes take almost
2% CPU load @500MHz just waiting on tick timer registers.

Also define new 34xx only registers.
