omap2 clock: init clksel clock parents to hardware reality at clock init
Source-selectable clksel clocks have a 'default parent' assigned to them
at compile-time. This default parent may or may not match the reality
that is configured in the hardware registers by the bootloader. Clock tree
recalculations could be erratic if the struct clk parent field contents
don't match the hardware registers.
Resolve this by creating omap2_init_clksel_parent() to read the hardware
registers and update the struct clk parent field as appropriate for clksel
clocks. Add an '.init' field to each source-selectable clk structure so
that the parent is fixed up when the clock is initially registered. (We
don't do this for clksel clocks that are only rate-selectable, since they
only have one possible parent clock.)

omap2 clock: add clksel and clksel_rate data
Many OMAP2 clocks are either source- or divisor-selectable by twiddling
various register bits; these are 'clksel' clocks. The table of rate divisors
and source clock settings was previously embedded in the clock.c source code.
Encode this data in two data structures:
1) struct clksel_rate for divisor-selection, mapping divisor values to
register bit field values, along with a flags field indicating which
chips the rate is available for -- one for each parent-rate combination; and:
2) struct clksel for source-selection, mapping parent struct clk pointers
to struct clksel_rate array pointers; one for each parent.
Also, add several fields to the clk structure:
1) clksel: pointer to the struct clksel array
2) clksel_reg: pointer to the clksel register
3) clksel_mask: mask for the clksel bitfield
Add this data to each clksel clock. All this data is not yet used by the clock
framework; that functionality is in the following patches.
N.B. Two clocks, sys_clkout and sys_clkout2, could not be converted to
this setup without splitting source selection and divisor selection.
This is because these clocks use separate registers for each
selector. So, create two new clocks, sys_clkout_src and
sys_clkout2_src, and locate source-selection there, and keep divisor
selection in sys_clkout/sys_clkout2. This entailed modifying
board-n800-audio.c.

omap2_propagate_rate() seems completely superfluous. It handles two
cases. The first case is for non-fixed rate clocks. It assigns the
parent's rate to the clock, and continues propagating the rate
downwards. This can be handled by adding a RATE_PROPAGATES clock flag
to the clock, if it wasn't there already, and by using
followparent_recalc() directly as the recalc function. The second
case is for fixed rate clocks. Here all we need to do is to call
propagate_rate() directly, so, use that for the recalc function.
