[PATCH v3 5/7] regulator: Remove mtk-dvfsrc-regulator.c

This driver never worked, and never got even compiled, because it was
missing the DVFSRC driver entirely, including headers it relies on!
In preparation of a full refactoring of this driver, remove it.
The Makefile and Kconfig entries are retained, as those are reused
as-is for the refactored code.
