Subject: watchdog: hpwdt: SMBIOS check

From: Jerry Hoemann <[email protected]>

commit c42cbe41727a138905a28f8e0b00c147be77ee93 upstream.

This corrects:
commit cce78da76601 ("watchdog: hpwdt: Add check for UEFI bits")

The test on HPE SMBIOS extension type 219 record "Misc Features" bits for UEFI support is incorrect. The definition of the Misc Features bits in the HPE SMBIOS OEM Extensions specification (and related firmware) was changed to use a different pair of bits to represent UEFI supported. Howerver, a corresponding change to Linux was missed.

Current code/platform work because the iCRU test is working. But purpose of cce78da766 is to ensure correct functionality on future systems where iCRU isn't supported.
