For boards with twl4030/tps65950 chips, update board setup code to
provide the appropriate board info.

This should evolve a bunch more over time; right now too much of this
data is globally defined (like IRQ and GPIO numbering).

More updates preparing for upstream merge of twl4030 driver:

 Basic fixes
   -	twl4030-core becomes a new-style I2C driver
   -	declare and use platform_data structure for that core
   -	stop hard-wiring the irq numbers
   -	check functionality that's really used:  I2C, not SMBus
 Cleanup:
   -	remove needless "client string"
   -	remove some fake "bool" types
   -	include catalog part numbers (TPS659{5,3,2}0)
   -	diagnostics should identify the driver!

To use this, all boards with these chips will need to declare this chip
when they declare their active I2C busses (done in a separate patch).

NOTE:  the TWL4030_IRQ_* symbols still need to vanish, along with other
global resource assignments associated with these chips.

For each OMAP module that has a target IDLEST bit, add the appropriate
bits to the clock tree on both the module interface clock and the appropriate
functional clock.  Add a new clock bit, "WAIT_READY", that indicates that
the clock code must wait for the clock's module to come out of idle after
both the target functional clock and interface clocks are enabled.  Fix
some clock flag comments while there to indicate that clocks marked
as "3430ES2" clocks also are valid for later 3430 revisions.

Several OMAP3xxx clocks must be split into platform-specific variants,
since some early silicon revisions do not have target idle state bits
available. DSS, HSOTGUSB, and SSI clocks are affected.  In the future, it
would be ideal to #ifdef out those clocks for kernels that don't need to
run on 3430ES1 chips to save memory.

Originally when the PRCM register macros were defined, bit shift macros
used a "_SHIFT" suffix, and mask macros used none.  This became a source
of bugs and confusion, as the mask macros were mistakenly used for shift
values.  Gradually, the mask macros have been updated, piece by piece,
to add a "_MASK" suffix on the end to clarify.  This patch applies this
change to the CM_IDLEST_* register bits.

The patch also adds a few bits that were missing, mostly from the 3430ES1
to ES2 revisions.

The DPLL's rate changes when it enters or leaves bypass, so the DPLL's

when this happens.
