pwm: brcmstb: Utilize appropriate clock APIs in suspend/resume
[ Upstream commit e9bc4411548aaa738905d37851a0146c16b3bb21 ]
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.
Fixes: 3a9f5957020f ("pwm: Add Broadcom BCM7038 PWM controller support")
