[PATCH v2] drm/i915/display: Print display info inside driver display initialization

[Balasubramani Vivekanandan <balasubramani.vivekanandan@xxxxxxxxx>]

Separate the printing of display version and feature flags from the main
driver probe to inside the display initialization. This is in alignment
with isolating the display code from the main driver and helps Xe driver
to resuse it.

v2: Replace drm_info_printer with drm_debug_printer (Jani)
