From: Alison Chaiken <alison@she-devel.com>

Add generalized support for setting arbitrary configuration of the
U-Blox Zed-F9P GNSS.  Employ the new functionality to set the baud rate
of the Zed-F9P if the devicetree specifies a non-default value.

Tested with 6.1.22 on U-Blox Zed-F9P GNSS devices.

V7 -> V8 Rebased on v6.4.
V6 -> V7 Fixed tag and version.
V5 -> V6 Change #ifdef to _maybe_unused and fix warnings.
V4 -> V5 Wrap all new code in a CONFIG_OF=y check and fixes
V3 -> V4 Lookup device-specific properties by matching driver data.
V2 -> V3 Add email recipients whom I foolishly missed the first two times.
V1 -> V2 Fixes error identified by kernel test robot:
