mb/google/volteer/variant/lindar: Disable acoustic mitigation
Roll back CPU slow slew rate setting to Intel default "SLEW_FAST_2"
Because baseboard modify slow slew rate setting to "SLEW_FASE_8"
for all project, but Lindar and Lillipup is using "SLEW_FAST_2",
so this setting need to roll back.
BUG=b:186140230
TEST=Build FW and boot to OS checking with CPU log.
