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).
