This patch cleans up arch/arm/mach-omap2/clkt_clksel.c. It:
- makes several functions static that are not called outside the file;
- adds documentation;
- makes some code paths easier to read (hopefully), by breaking up
compound statements and removing redundant checks;
- converts some pr_err()s that indicate clock tree data problems into WARN()s,
so they are more likely to be noticed;
- and moves omap2_clk_round_rate() back into mach-omap2/clock.c, its proper
home, since it is not clksel-specific.

The DEFAULT_RATE clksel_rate flag is essentially useless. It was set
on some of the lowest divisors, which, when switching to a much
higher-rate parent, could have potentially resulted in rates that
exceeded the hardware specifications for downstream clocks in the
window between the clk_set_parent(), and a subsequent clk_set_rate().
It seems much safer to just remove the flag and always use the highest
available divisor (resulting in the lowest possible rate) after the
switch, and this patch does so.
Ideally, it would be best to first attempt to switch to a divisor that
matches the clock's rate with the previous parent, if at all possible.
But that is a project for some other day or some other person. The
parent changing code is rarely used.

Writes to the PM_*GRPSEL registers should use _GRPSEL_ macros, not _EN_ macros,

Fix all of the remaining 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.

I believe the VMMC2 constraints must be the same than with VAUX3. Older
boards are using TWL4030 VMMC2 supply for internal MMC whereas newer are
using VAUX3 that has more limited constraints defined in this same file.
More over, the VMMC2 supply is used also for analog audio domain and the
miminum analog voltage of the TLV320AIC34 codec is 2.7 V.
To combine these two facts, the patch changes supply name to V28_A as the
newer boards register VMMC2_30 for VAUX3 and uses the same constraints than
VAUX3 since those constraints are ok for the TLV320AIC34.
