clk: ti: convert to use proper register definition for all accesses

Currently, TI clock driver uses an encapsulated struct that is cast into
a void pointer to store all register addresses. This can be considered
as rather nasty hackery, and prevents from expanding the register
address field also. Instead, replace all the code to use proper struct
in place for this, which contains all the previously used data.

This patch is rather large as it is touching multiple files, but this
can't be split up as we need to avoid any boot breakage.

clk: ti: dpll: convert DPLL support code to use clk_hw instead of clk ptrs

Convert DPLL support code to use clk_hw pointers for reference and bypass
clocks. This allows us to use clk_hw_* APIs for accessing any required
parameters for these clocks, avoiding some locking problems at least with
DPLL enable code; this used clk_get_rate which uses mutex but isn't
good under clk_enable / clk_disable.

Merge branch 'for-4.2/ti-clk-move' of https://github.com/t-kristo/linux-pm into clk-next

From Tero Kristo:
"This pull request contains the TI clock driver set to move the
clock implementations under clock driver. Some small portions of
the clock driver code still remain under mach-omap2 after this,
it should be decided whether this code is now obsolete and should
be deleted or should someone try to fix it."

Slight merge conflicts with determine_rate prototype changes.
