    mediatek: pinctrl-mt7988: add missing PWM pingroups
    
    Add additionals possible pinctrl group for pwm2~7 on pins
    pin  4 (GPIO_A)        pwm7
    pin 58 (JTAG_JTDI)     pwm2
    pin 59 (JTAG_JTDO)     pwm3
    pin 60 (JTAG_JTMS)     pwm4
    pin 61 (JTAG_JTCLK)    pwm5
    pin 62 (JTAG_JTRST_N)  pwm6
    
    They can be useful e.g. on the BPi-R4 as in that way pwm2~6 can be exposed
    on the 26-pin header (pwm6 always, pwm2~5 instead of the full UART).
