[PATCH v2 2/2] hwmon: intel-m10-bmc-hwmon: add sensor support of Intel D5005 card

[matthew.gerlach@xxxxxxxxxxxxxxx]

From: Matthew Gerlach <matthew.gerlach@xxxxxxxxxxxxxxx>

Like the Intel N3000 card, the Intel D5005 has a MAX10 based
BMC.  This commit adds support for the D5005 sensors that are
monitored by the MAX10 BMC.
