[PATCH rtw-next] wifi: rtw88: Fill fw_version member of struct wiphy

[Bitterblue Smith]

Let userspace tools like lshw show the firmware version by filling the
fw_version member of struct wiphy.

Before:

configuration: broadcast=yes driver=rtw88_8814au
driverversion=6.19.6-arch1-1 firmware=N/A link=no multicast=yes
wireless=IEEE 802.11

After:

configuration: broadcast=yes driver=rtw88_8814au
driverversion=6.19.6-arch1-1 firmware=33.6.0 link=no multicast=yes
wireless=IEEE 802.11
