[PATCH rtw-next 2/3] wifi: rtlwifi: convert pci ID if-statement to table

[William Hansen-Baird <william.hansen.baird@gmail.com>]

Refactor the ASUSTek quirk logic from an if-statement to a standard
pci_device_id table. This allows future devices with the same quirk
to be added more easily and avoiding a large if-chain.
