Originally we enable a special gate bit when the compatible indicates A23/33.
But according to BSP sources and user manuals, more SoCs will need this gate bit.
So make it a common quirk configured in the config struct.
The BSP source also indicates that A83T will need this gate bit (there's "SUN8IW6" in the #ifdef's), so also enable this gate bit for it.
