pwm: rcar: Drop of_match_ptr for ID table

The driver can match only via the DT table so the table should be always
used and the of_match_ptr does not have any sense (this also allows ACPI
matching via PRP0001, even though it might not be relevant here). This
also fixes the following compiler warning:

  drivers/pwm/pwm-rcar.c:252:34: error: ‘rcar_pwm_of_table’ defined but not used [-Werror=unused-const-variable=]

for builds with CONFIG_OF=n, CONFIG_PWM_RCAR=y and W=1.
