Fabrice Gasnier 3066bc2d58 pwm: stm32-lp: fix the check on arr and cmp registers update 
The ARR (auto reload register) and CMP (compare) registers are
successively written. The status bits to check the update of these
registers are polled together with regmap_read_poll_timeout().
The condition to end the loop may become true, even if one of the
register isn't correctly updated.
So ensure both status bits are set before clearing them.
