[PATCH 2/6] igt_kms: pass drm_fd instead of igt_display_t on some functions

[Paulo Zanoni <przanoni@xxxxxxxxx>]

From: Paulo Zanoni <paulo.r.zanoni@xxxxxxxxx>

Since these functions only really use the drm_fd. The goal is to be
able to reuse these functions on programs that don't use the
igt_display_t structure.
