[PATCH v2 1/2] mac80211: split rtw88 configuration for each supported chip

[Alexis Lothoré]

From: Alexis Lothoré <alexis.lothore at bootlin.com>

Current rtw88 build configuration builds modules for all chips supported by
rtw88 driver family. This brings the following issues:
- adding a chip with a different bus is not convenient (all chips currently
  depends on PCI)
- some features requirements are not relevant for all chips in family (eg
  802.11AC is enforced but RTW88-8723DE is only a 802.11b/g/n chip)

Remove those constraints/issues by adding one module build option per
supported chip, and add intermediate options to properly cascade
dependencies.
