[PATCH 5/9] staging: sm7xxfb: minor maintenance on sm7xx_vga_setup

[Javier M. Mellid]

From: "Javier M. Mellid" <jmunhoz at igalia.com>

This patch keeps code related to sm7xx_vga_setup closed. It is useful to
understand/maintain the logic behind sm7xx_vga_setup with a simple look.

Tested with SM712.
