pwm: brcmstb: Utilize appropriate clock APIs in suspend/resume 

[ Upstream commit e9bc441154 ]

The suspend/resume functions currently utilize
clk_disable()/clk_enable() respectively which may be no-ops with certain
clock providers such as SCMI. Fix this to use clk_disable_unprepare()
and clk_prepare_enable() respectively as we should.
