mb/google/rex: Enable Fast V-Mode for MTL-U 15W
This patch sets the FVM configuration parameter as suggested in Intel doc 640982. As per the doc, Intel MTL-P 28W CPU supports FVM on IA, GT 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 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 Icc max for IA is 91A, 53A for GT and 35A for SA.
BUG=b:286809233 TEST=Able to build and boot google/rex without seeing any performance regression.
