[PATCH i-g-t v2 10/15] tests/kms_big_fb: Replace 'bpp' with 'name'

[Ville Syrjala <ville.syrjala@linux.intel.com>]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Instead of storing the bpp in the formats[] array let's instead
store a string represtantion. I want to add planar YCbCr tests
to the mix, and so a simple bpp value will no logner cut it.

A bunch of stuff is using the numerical bpp value for some things,
but we can replace those with igt_drm_format_to_bpp().
