[PATCH v4 4/4] pwm: tiehrpwm: drop unnecessary parentheses and fix spacing

["Rafael V. Volkmer" <rafael.v.volkmer@gmail.com>]

The comparison in pwm-tiehrpwm.c triggered “UNNECESSARY_PARENTHESES” and
“PARENTHESIS_ALIGNMENT” when wrapping the second clause in extra parens.
This removes superfluous parentheses, aligns continued lines under the ‘if’,
and ensures operators are properly spaced.
