Fix all of the remaining OMAP3 PRCM register shift/bitmask macros that
did not use the _SHIFT/_MASK suffixes to use them.  This makes the use
of these macros consistent.  It is intended to reduce error, as code
can be inspected visually by reviewers to ensure that bitshifts and
bitmasks are used in the appropriate places.

In 3630, DPLL4M2 output can be 96MHz or 192MHz (for SGX to run at
192). This patch has changes to support this feature. 96MHz clock is
generated by dividing 192Mhz clock by 2 using CM_CLKSEL_CORE register.
SGX can select Core Clock, 192MHz clock or CM_96M_FCLK as it's
functional clock. In summary changes done are:
1. Added a feature called omap3_has_192mhz_clk and enabled for 3630
2. Added a new clock node called omap_192m_alwon_ck
3. Made omap_96m_alwon_fck to derive its clock from omap_192m_alwon_ck

Divider (M2, M3, M4, M5 and M6) field width has been increased by 1 bit
in 3630. This patch has changes to accommodate this in CM dynamically
based on chip version.
Basically new clock nodes have been added for 3630 DPLL4 M2,M3,M4,M5 and
M6 and value of these nodes are used if cpu type is 3630.

DPLL4 for 3630 introduces a changed block called j type dpll, requiring
special divisor bits and additional reg fields. To allow for silicons to
use this, this is introduced as a flag and is enabled for 3630 silicon.
OMAP4 also has j type dpll for usb.

Tested with 3630 ZOOM3 and OMAP3430 ZOOM2

Add D2D clocks (modem_fck, sad2d_ick, mad2d_ick) to clock framework
and ensure that auto-idle bits are set for these clocks during PRCM
init.

Also add omap3_d2d_idle() function called durint PRCM setup which
ensures D2D pins are MUX'd correctly to enable retention for
standalone (no-modem) devices.

This patch fixes a few OMAP2xxx CM_IDLEST bits that were incorrectly
marked as being OMAP2xxx-wide, when they were actually 2420-specific.

Also, 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 GFX/SGX functional and interface clocks have different masks, for
some unknown reason, so split EN_SGX_SHIFT into one each for fclk and
iclk.

Correct according to the TRM and the far more important 'does this
actually work at all?' metric.

Fix some bugs in the OMAP3 clock tree pertaining to the 96MHz clocks.
The 96MHz portion of the clock tree should now have reasonable
fidelity to the 34xx TRM Rev I.

One remaining question mark: it's not clear exactly which 96MHz source
clock the USIM uses.  This patch sticks with the previous setting, which
seems reasonable.

This patch adds support for DPLL autoidle control to the OMAP3 clock
framework.  These functions will be used by the noncore DPLL enable
and disable code - this is because, according to the CDP code, the
DPLL autoidle status must be saved and restored across DPLL
lock/bypass/off transitions.

N.B.: the CORE DPLL (DPLL3) has three autoidle mode options, rather
than just two.  This code currently does not support the third option,
low-power bypass autoidle.

These changes is the result of the discussion with Paul Walmsley.
His ideas are included into this patch.

Remove DPLL output divider handling from DPLLs and CLKOUTX2 clocks,
and place it into specific DPLL output divider clocks (e.g., dpll3_m2_clk).
omap2_get_dpll_rate() now returns the correct DPLL rate, as represented
by the DPLL's CLKOUT output. Also add MPU and IVA2 subsystem clocks, along
with high-frequency bypass support.

Add support for DPLLs function in locked and bypass clock modes.
