mei: add trc detection register to sysfs
The glitch detection HW (TRC) save it status information into
TRC status register.
Make it available to user-space via read-only sysfs file.
The TRC register is availab for PCH15 gen and newer, for older
platforms reading the sysfs file will fail with EOPNOTSUPP.
