6.1-stable review patch. If anyone has any objections, please let me know.

[ Upstream commit ea861df772fd8cca715d43f62fe13c09c975f7a2 ]
Some of the regulators on the MT6358/MT6366 PMICs have just one linear voltage range. These are the bulk regulators and VSRAM_* LDOs. Currently they are modeled with one linear range, but also have their minimum, maximum, and step voltage described.
Convert them to the linear voltage helpers. These helpers are a bit simpler, and we can also drop the linear range definitions. Also reflow the touched lines now that they are shorter.
