I'd like you to reexamine a change. Please visit

to look at the new patch set (#15).
Change subject: mediatek/mt8183: Calibrate vsim2 to 2.7 V ......................................................................
mediatek/mt8183: Calibrate vsim2 to 2.7 V
The default voltage of vsim2 is set to 2.76V for sim card usage. In general, 2.76V of vsim2 is composed of 2.7V main voltage and 0.06V calibration voltage. However, vsim2 is used for the tx_ovdd power of display port IT6505 on the kukui board design which needs 2.7V. So we set it to 2.7V with modifying calibration value.
BUG=b:126139364 BRANCH=none TEST=measure vsim2 voltage with multimeter
