With non-contiguous pipes display, pipe mapping is always not same as
crtc mapping, For i915 pipe is enum id of i915's crtc object and
it is not equal to crtc offset of a pipe in mode config list.
Hence allocating upper bound array for igt_pipe and reading
pipe id using GET_PIPE_FROM_CRTC_ID ioctl.
Using crtc offset for a pipe to do ordering pipe with crtc list.

Example:
With a non-contiguous pipe display, with PIPE_A & PIPE_D
are enabled, PIPE_C & PIPE_B disabled configuration,
the pipe for PIPE_A & D will be '0' and '3' and crtc offsets
are '0' & '1' in mode config list using crtc offset to ordering
enabled pipes with crtc list in mode config.

Modified documentation as per review comments by <Hiler, Arkadiusz>
