arm64: dts: mediatek: mt6358: fix dtbs_check error

[ Upstream commit 76ab2ae0ab9ebb2d70e6ee8a9f59911621192c37 ]

Fix DTBS check errors for 'mt6358codec' and 'mt6358regulator':

Error message is:
pmic: 'mt6358codec' and 'mt6358regulator' does not match any of the
regexes: 'pinctrl-[0-9]+'.
Rename these two device node to generic 'audio-codec' and 'regulators'.
