x86_64: configure MSRs needed by intel_pstate in initramfs

HWP CPUID bits are decoupled from ITMT feature and the related MSRs are
passthru to ChromeOS by default, thus we no longer need to setup HWP
MSRs at the time of enabling ITMT or PnP.

BUG=b:199380745
TEST=boot Redrix manatee and verified that all related features work

crosvm - The Chrome OS Virtual Machine Monitor

crosvm is a virtual machine monitor (VMM) based on Linux’s KVM hypervisor, with a focus on simplicity, security, and speed. crosvm is intended to run Linux guests, originally as a security boundary for running native applications on the Chrome OS platform. Compared to QEMU, crosvm doesn’t emulate architectures or real hardware, instead concentrating on paravirtualized devices, such as the virtio standard.

crosvm is currently used to run Linux/Android guests on Chrome OS devices.
