pwm: clps711x: Drop of_match_ptr() usage for .of_match_table

The pwm-clps711x driver depends on ARCH_CLPS711X || COMPILE_TEST. With
the former being an ARCH_MULTI_V4T platform, there is always OF=y when
ARCH_CLPS711X=y, so in practise clps711x_pwm_dt_ids[] is always used.
(And in the case COMPILE_TEST=y + OF=n this only increases the driver
size a bit but still compiles.)

So drop the usage of of_match_ptr().
