mb/google/rex: Enable Fast V-Mode for MTL-U 15W
This patch sets the Fast V-Mode (FVM) configuration parameter as suggested in Intel doc 640982. As per the doc, Intel MTL-U 15W CPU supports FVM on IA and SA.
Fast V-Mode (FVM): Intel Meteor Lake introduces the ability to manage the peak power events it calls "reactive peak power management".
The Fast V-Mode is one such technique to perform the reactive peak power management. It relies on the detector integrated inside the processor which senses when the processor load current exceeds a present threshold by monitoring the processor power domain IMVP (Intel Mobile Voltage Positioning) VR sense point.
The baseline ITRIP for IA is 70A and 35A for SA.
BUG=b:286809233 TEST=Able to build and boot google/rex without seeing any performance regression.
