Subject: [PATCH 2/7] dt-bindigns: regulator: mtk: Drop unneeded compatible

From: Matthias Brugger <mbrugger@...e.com>

The regulator does not need to have a device tree compatible, if it's
part of an MFD. We leave the node name to the SoC specific name (e.g.
mt6323regulator) to allow older kernels to work with the new binding.
