pwm: meson: Drop always false check from .request()
In .request() pwm_get_chip_data() returns NULL always since commit
e926b12c611c ("pwm: Clear chip_data in pwm_put()"). (And if it didn't
returning 0 would be wrong because then .request() wouldn't reenable
the clk which the other driver code depends on.)
