drm/ast: Move Gen4 device initialization into separate helper

Browse source

Split off device initialization for Gen4 hardware into the helpers
ast_2300_device_create() and ast_2300_detect_wide_screen(). The new
functions are duplicates of their counterparts in ast_main.c, but
stripped from most non-Gen4 support.

Simplifies maintenance as the driver's number of supported hardware
generations grows.

v2:
- simplify widescreen-detection logic
