commit 316e361b5d2cdeb8d778983794a1c6eadcb26814 upstream.
The "groups" property can hold multiple entries (e.g.
toshiba/tmpv7708-rm-mbrc.dts file), so allow that by dropping incorrect
type (pinmux-node.yaml schema already defines that as string-array) and
adding constraints for items. This fixes dtbs_check warnings like:
toshiba/tmpv7708-rm-mbrc.dtb: pinctrl@24190000 (toshiba,tmpv7708-pinctrl):
pwm-pins:groups: ['pwm0_gpio16_grp', 'pwm1_gpio17_grp', 'pwm2_gpio18_grp', 'pwm3_gpio19_grp'] is too long
Fixes: 1825c1fe00 ("pinctrl: Add DT bindings for Toshiba Visconti TMPV7700 SoC")
