When the OMAP patches are applied and the kernel is built for a
non-ARM target, there are a handful of Kconfig warnings due to the use
of OMAP_MCBSP in arch-independent Kconfig files.

This patch simply removes the 'select OMAP_MCBSP' in these
arch-independent files since it is already 'default y' in

mdm_osc_ck has a preinitialized rate and is marked as RATE_FIXED, but rather
than using omap2_propagate_rate() as its recalc function, which accounts
for RATE_FIXED clocks, it uses omap2_followparent_recalc(), which sets the
rate to the parent clock's rate.  After reviewing the 2430 TRM, fix this
inconsistency by removing the fixed rate declarations (TRM says that this
clock is 'typically' 26MHz).

The rates of some clocks are equal to their parents' rates, divided by some
fixed integer.  This contrasts with the existing 'followparent' clocks,
which follow their parents' rates strictly; and the existing 'clksel' clocks,
which follow their parents' rates divided by a runtime-selectable divisor.
Add code to implement these clocks without resorting to specifying a
fixed rate.

If the clock framework can't figure out how to enable a clock, return
-EINVAL to indicate that the clock cannot be enabled.  Previously the
code returned 0, which indicated success.

Also fix the "clock.c: Enable for dpll_ck without enable code" boot
warning by marking dpll_ck as ALWAYS_ENABLED.  This is not technically
true, since the DPLL can be bypassed; but since we currently have no
software infrastructure to control it directly, ALWAYS_ENABLED is a
sufficient fiction for dpll_ck.

The clock framework currently uses a magic value in struct clk
.enable_bit to indicate that the clock's parent controls enabling and
disabling the clock.  There's no need to use this type of in-band
special value when there's already a good means to indicate binary
clock parameters: the clock flags field.  This patch converts the
existing PARENT_CONTROLS_CLOCK code to use a clock flag.

vlynq_fck is a clksel clock, so its rate is equal to its parent's
rate, divided by whichever divisor is selected.  But its definition in
clock.h specifies omap2_followparent_recalc() as its rate calculation
code, which sets the clock's rate to that of its parent without
accounting for any divisor.  Fix to use omap2_clksel_recalc() instead.

For clksel clocks, omap2_clk_set_rate() incorrectly divides the parent
clock's rate by the actual bits of the register field, rather than the
translated divisor value.  This happens to work for most clksel
clocks, since the register bit fields are equal to the divisor values.
But for some clocks, such as sys_clkout, the code gets the resulting
rate wrong.
