Finish removing dependency of TWL driver stack on platform-specific
IRQ definitions ... and remove the build dependency on OMAP.

This lets the TWL4030 code be included in test builds for most
platforms, and will make it easier for non-OMAP folk to update
most of this code for new APIs etc.

Disable the TWL4030_PWRIRQ_PWRBTN symbol from the system headers;
initialization of the power button handler still needs work, so
an equivalent symbol is defined in its driver.

Power IRQs now properly handle trigger specs from request_irq();
stop goofing with registers reserved to the IRQ infrastructure.

Minor cleanup:  switch several messages to pr_debug().

Add init data for the LDO regulators used on Beagle boards:

 - VMMC1 is the main MMC1 power
 - VSIM powers MMC1 too:  DAT4-DAT7 pins, for HSMMC cards
 - VDAC for S-Video output

Those regulators need to be hooked up to the MMC1 and FB (?) devices
through the regulator framework.

Initial code to create twl4030 voltage regulator devices, using
the new regulator framework.  Note that this now starts to care
what name is used to declare the TWL chip:

 - TWL4030 is the "old" chip; newer ones have a bigger variety
   of VAUX2 voltages.

 - The tps65930 and tps65920 are cost-reduced catalog versions of
   the TWL5030 parts ... fewer regulators, no BCI, etc.  (Rev C
   Beagles were anticipated to use '930 parts...)

Board-specific regulator configuration should be provided, listing
which regulators are used and their constraints (e.g. 1.8V only).

Code that could ("should"?) leverage the regulator stuff includes
twl4030 USB transceiver support and MMC glue, LCD support for the
3430SDP and Labrador boards, and S-Video output.

During _omap3_noncore_dpll_lock(), if a DPLL has no active downstream
clocks and DPLL autoidle is enabled, the DPLL may never lock, since it
will enter autoidle immediately.  To resolve this, disable DPLL
autoidle while locking the DPLL, and unconditionally wait for the DPLL
to lock.  This fixes some bugs where the kernel would hang when returning
from retention or return the wrong rate for the DPLL.

<peter.de-schrijver@nokia.com> and Kevin Hilman
<khilman@deeprootsystems.com>.

The DPLL FREQSEL jitter correction bits are set based on a table in
the 34xx TRM, Table 4-38, according to the DPLL's internal clock
frequency "Fint."  Several Fint frequency ranges are missing from this
table.  Previously, we allowed these Fint frequency ranges to be
selected in the rate rounding code, but did not change the FREQSEL bits.
Correspondence with the OMAP hardware team indicates that Fint values
not in the table should not be used.  So, prevent them from being
selected during DPLL rate rounding.  This removes warnings and also
can prevent the chip from locking up.

The first pass through the rate rounding code will update the DPLL max
and min dividers appropriately, so later rate rounding passes will run
faster than the first.

The previous DPLL rate rounding algorithm counted the divider (N) down
from the maximum to 1.  Since we currently use a broad DPLL rate
tolerance, and lower N values are more power-efficient, we can often
bypass several iterations through the loop by counting N upwards from
1.

i2c-omap discriminates only between "revision 1" or "greater than
revision 1."  A following patch introduces code that must also
discriminate between rev2.x, rev3.6, and rev3.12 controllers.  Support
this by storing the full revision data from the I2C_REV register, rather
than just a single bit.

The revision definitions may need to be extended for other ES levels
that aren't currently available here.  rev3.6 is what's present on the
2430SDP here (unknown ES revision); rev3.12 is used on the 3430ES2
here.
