Subject: [PATCH v2 1/7] mfd: mt6358: Add missing registers for LDO voltage calibration

Most of the LDOs, except the "VSRAM_*" ones, on the MT6358 and MT6366
PMICs support a finer output voltage calibration within the range of
+0 mV to +100 mV with 10 mV step. Some of the registers for this
function are missing from the register table.

Add the missing ones for MT6358.
