Use the clk->prcm_mod field for all register addresses in struct clk.
Remove all usage of the *_REGADDR() and *_OFFSET() macros from the
clock tree.  This eliminates a set of (__force void __iomem *) casts
and removes all of the OMAP2xxx register address rewriting.  Shrink
the width of the enable_reg/clksel_reg registers to 16 bits, saving 4
bytes per struct clk.

McBSP clock source control registers are located in the System Control
Module, not the PRCM.  However, the clock enable/disable registers are
in the CM.  Since the following patches require all registers in a
struct clk to be in only one of {CM, PRM, SCM}, we must split the
source clock selection into a separate struct clk from the clock
enable/disable control.

The DPLL's rate changes when it enters or leaves bypass, so the DPLL's
rate and the rates of all dependent clocks need to be recalculated
when this happens.

Also, fix test for bypass to test against the appropriate bypass clock,
rather than the parent clock (which is not the bypass clock for DPLL1
and DPLL2).

Most DPLLs use sys_clk as their bypass rate source.  But DPLL1 and DPLL2
use high-frequency bypass clocks dpll1_fclk and dpll2_fclk as their parents
during bypass.  Add a new struct dpll_data field to track the DPLL's bypass
source clock.
