dt-bindings: pinctrl: mt8186: Add and use drive-strength-microamp
Commit e5fabbe43f3f ("pinctrl: mediatek: paris: Support generic
PIN_CONFIG_DRIVE_STRENGTH_UA") added support for using
drive-strength-microamp instead of mediatek,drive-strength-adv.
Similarly to the mt8192 and mt8195, there's no user of property
'mediatek,drive-strength-adv', hence removing it is safe.
