pwm: Reduce number of pointer dereferences in pwm_device_request()
pwm->chip and pwm->chip->ops are used several times in this function.
Introduce local variables for these.
There is no semantical change, but with ARCH=arm, allmodconfig and
gcc-13 bloat-o-meter reports a slight improvement:
add/remove: 1/1 grow/shrink: 1/1 up/down: 8/-36 (-28)
