[PATCH] drm/amd/display: use swap() helper macro in bios_parser

[Deepak R Varma]

Use swap() helper macro instead of open coded swap instructions. The
change also facilitates code cleanup and realignment for improved
readability.  Issue identified using swap.cocci Coccinelle semantic
patch script.
