arm64: dts: mediatek: mt8186-corsola-voltorb: Merge speaker codec nodes

The Voltorb device uses a speaker codec different from the original
Corsola device. When the Voltorb device tree was first added, the new
codec was added as a separate node when it should have just replaced the
existing one.

Merge the two nodes. The only differences are the compatible string and
the GPIO line property name. This keeps the device node path for the
speaker codec the same across the MT8186 Chromebook line. Also rename
the related labels and node names from having rt1019p to speaker codec.
