This patch series adds hardware monitoring support to the fbnic driver.
It implements support for reading temperature and voltage sensors via
firmware requests, and exposes this data through the HWMON interface.

The series is structured as follows:

Patch 1: Adds completion infrastructure for firmware requests
Patch 2: Implements TSENE sensor message handling
Patch 3: Adds HWMON interface support

Output:
