Initialize brightness_set and blink_set callbacks to
mt7615_led_set_brightness and mt7615_led_set_blink in order to enable
LED support in mt7615 driver
Tested-by: Deng Qingfang <dengqf6@xxxxxxxxxxxxxxxxx>
Signed-off-by: Lorenzo Bianconi <lorenzo@xxxxxxxxxx>

Changes since v2:
- remove _MASK suffix from register definitions and move the code in init.c
Changes since v1:
- rely on FIELD_PREP for LED register definitions
