pinctrl: pinctrl-single: add ti,am62l-padconf compatible string

Add "ti,am62l-padconf" compatible string for the AM62L SoC, which
requires register configurations to be restored during system resume
after suspend to RAM (RTC only + DDR mode). This reuses the j7200
configuration which includes the PCS_CONTEXT_LOSS_OFF flag needed for
proper restoration.
