[Intel-gfx] [PATCH 2/2] drm/i915/guc: Turn on GuC/HuC auto mode

[Joonas Lahtinen]

> Using "enable_guc" modparam auto mode (-1) will let driver
> decide on which platforms and in which configuration we want
> to use GuC/HuC firmwares.
> 
> Today driver will enable HuC firmware authentication by GuC
> only on Gen11+ platforms as HuC firmware is required to unlock
> advanced video codecs in media driver.
> 
> Legacy platforms with GuC/HuC are not affected by this change
> as for them driver still defaults to disabled(0) in auto mode.
