Subject: [PATCH v2 1/2] 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 !CONFIG_OF error:

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