Make these const as they are only stored in the const field of a
clk_init_data structure.

CLK: SPEAr: make aux_clk_masks structures const

Make these const as they are either stored in the masks 'const' field
of a clk_aux structure or passed to the function clk_register_aux
having the argument as const.

CLK: SPEAr: make structure field and function argument as const

Make the masks field of clk_aux structure const as it do not modify the
fields of the aux_clk_masks structure it points to.

Make the struct aux_clk_masks *aux argument of the function
clk_register_aux as const as the argument is only stored in the masks
field of a clk_aux structure which is now made const.

Update Viresh Kumar's email address

Switch to my kernel.org alias instead of a badly named gmail address,
which I rarely use.

CLK: SPEAr: Set CLK_SET_RATE_PARENT for few clocks

Flag CLK_SET_RATE_PARENT is required for a clock, where we want to
propagate clk_set_rate to its parent. This patch adds this to multiple clocks.

SPEAr: clk: Add Auxiliary Synthesizer clock

All SPEAr SoC's contain Auxiliary Synthesizers. Their Fout is derived based on
values of eq, x and y.

Fout from synthesizer can be given from two equations:
Fout1 = (Fin * X/Y)/2 EQ1
Fout2 = Fin * X/Y EQ2

This patch adds in support for this type of clock.
