Subject: [PATCH v5 6/6] pwm: tiehrpwm: tidy prescale calculation style

Tidy ehrpwm_pwm_config(): drop redundant parentheses, keep the condition
on a single line, and add spacing around the division operator to follow
kernel style.

This change addresses a style warning reported by checkpatch.pl.
No functional change intended.
