The current driver calculates the clock divider with
fractional support enabled.
But it does not enable fractional support in the
control register itself resulting in an integer only divider,
but in clk_set_rate responds back the fractionally divided
clock frequency.
This patch enables fractional support in the control register
whenever there is a fractional bit set in the requested clock divider.
Mash clock limits are are also handled for the PWM clock
applying the correct divider limits (2 and max_int) applicable to
basic fractional divider support (mash order of 1).
It also adds locking to protect the read/modify/write cycle of
the register modification.
