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.

Convert omap2_get_clksel to use void __iomem *.  Add
omap2_divisor_to_clksel(), to convert clock divisors into appropriate
register bit field values.  Use non-shifted register bit field masks
in clksel code, rather than masks that have been preshifted down to
bit 0 -- this simplifies existing code and facilitates the use of
symbolic constants from the recent PRCM cleanup.  Also add code to
properly handle divisors for sys_clkout2 on OMAP2420.  Previously
this clock's divisor settings were ignored.

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.
omap2_clksel_recalc() is also missing the appropriate special case to
divide the vlynq_fck rate down; add this in.

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.
