[igt-dev] [RFC i-g-t 0/1] test/kms: Use bare number of crtc index to get a pipe

[Mohammed Khajapasha]

In non-continous pipe display,
1. if PIPE_B,C is disabled in kernel, PIPE_A & PIPE_D
get registered with 0,1 indexes in display pipes[] array
and kmstest_pipe_name() always prints PIPE_B for enum pipe 1
which is actually PIPE_D in kernel.
2. And in kernel the possible_crtc bit map is based on
crtc index and for PIPE_D second least bit set in possible_crtc,
macro for_each_pipe_with_valid_output() with enum pipe index
always assumes PIPE_B for second least bit in possible_crtc
but it is PIPE_D in kernel.

To avoid this using bare number of crtc index
to get a pipe from display->pipes[] array to support
non-continuous pipe display.
This is a sample change to review on usage of bare number of
https://patchwork.freedesktop.org/series/74431/
crtc index for each pipe, based upon the review the patch series
will be updated with this change.
