[PATCH] mtrr: set severity to critical for incorrect attributes

[Alex Hung]

The lpss device driver crashes OS when its PCI BAR ranges are set to
write-combining in MTRR. The errors was caught as below, but they were
medium failures and ignored. Therefore, change it to critical.

Medium failures: 3
 mtrr: Memory range 0x4010000000 to 0x4010000fff (0000:00:15.0) has incorrect attribute Write-Combining.
 mtrr: Memory range 0x4010001000 to 0x4010001fff (0000:00:15.1) has incorrect attribute Write-Combining.
 mtrr: Memory range 0x4010002000 to 0x4010002fff (0000:00:1e.0) has incorrect attribute Write-Combining.
