module parameter documentation

[beroal]

Hi. Thank you for supporting this driver. It'd be great to include a documentation for some module parameters; see the documentation for an alternative driver by morrownr. I personally tried to enable a 80 MHz channel in the AP mode in the 5 GHz band for several months before discovering the parameter rtw_vht_enable=2. Other people may benefit from the knowledge of other parameters. Some parameters are documented in /os_dep/linux/os_intfs.c in the source code, so you can insert the documentation there. It's where I found the documentation for rtw_dfs_region_domain, for example.

First, I installed morrownr's driver, but then I noticed that rtw_vht_enable works with your driver. I prefer your driver since you created an ArchLinux package. Thank you again.

I tested your driver with kernel 5.12.6, so you can update README.md.

I may add a few parameters docs, but you can list them by using modinfo 88x2bu.

This is what I've done, but parameter names without docs aren't really useful. ☹
