[0/8] drm/ast: Reorganize TX-chip detection and init

Message

Detection and initialization of TX chips is mixed up with each other
and other device-probing code. Move it into one place and reorganize
branches by Aspeed Gen.

This series is another step towards separating the TX code from the
rest of the driver and making each hardware gen self-contained.

Tested on AST 1100, 2300, 2500 and 2600.

Thomas Zimmermann (8):
  drm/ast: Detect wide-screen support before creating modeset pipeline
  drm/ast: Detect DRAM before TX-chip
  drm/ast: Refactor ast_post_gpu() by Gen
  drm/ast: Initialize ASTDP in ast_post_gpu()
  drm/ast: Hide Gens 1 to 3 TX detection in branch
  drm/ast: Align Gen1 DVO detection to register manual
  drm/ast: Merge TX-chip detection code for Gen4 and later
  drm/ast: Only warn about unsupported TX chips on Gen4 and later
