From PTL we need to move to using HDCP2_STREAM_STATUS as a WARN_ON
to see if written content type info is not the same since
HDCP2_AUTH_STREAM is inaccessible to us now.

Display code should not care about graphics version. While at it,
abstract the version check to a separate macro.

Split out the display register helper macros to a separate file. For
now, include it from i915_reg.h, but note that there are already files
that don't need i915_reg.h, such as intel_audio.c.

Registers contents are supposed to be defined using REG_BIT() to ensure
they're u32 and the shift is within bounds.

Reduce the bloat of i915_reg.h. The registers are also only needed in a
few places, no need to have them defined everywhere.
