Subject: [PATCH] BM/FRED: Remove kernel cmdline fred=on check and dmesg check

From kernel 7.1-rc1, FRED is enabled by default only if
CONFIG_X86_FRED=y in Kconfig, no need to add fred=on in kernel
cmdline, and FRED initialization info is removed from dmesg either.

(cherry picked from commit 91f35fc76e7fa213ca45b9cccfbd076ed87b1d7e)
