zephyr: mtk power sequence code refactor

Minor refactor before landing mt8186 power seq:

1) remove PLATFORM_EC_POWERSEQ_IT8XXX2, we don't have common power code
   for it8xxx2 devices currently.
2) rename mediatek,power-signal-list dts binding to mt8192.

Powerseq for MTK platform should infer from AP_ARM_MTK_MTxxxx, not from
the EC chip.

BUG=b:206338930
TEST=1) zmake -j32 configure -b zephyr/projects/asurada/hayato/
     2) zmake -j32 configure -b zephyr/projects/corsola/krabby/
