wifi: mt76: mt76x2: Add support for LiteOn WN4516R,WN4519R

Browse Source 
[ Upstream commit 3c0e4f606d8693795a2c965d6f4987b1bfc31097 ]

Adds support for:
 - LiteOn WN4516R
 - LiteOn WN4519R
 Both use:
 - A nonstandard USB connector
 - Mediatek chipset MT7600U
 - ASIC revision: 76320044

Disabled VHT support on ASIC revision 76320044:

 This fixes the 5G connectibity issue on LiteOn WN4519R module
 see https://github.com/openwrt/mt76/issues/971

 And may also fix the 5G issues on the XBox One Wireless Adapter
 see https://github.com/openwrt/mt76/issues/200

 I have looked at the FCC info related to the MT7632U chip as mentioned in here:
 https://github.com/openwrt/mt76/issues/459
 These confirm the chipset does not support 'ac' mode and hence VHT should be turned of.
