kms_pipe_crc_basic: Remove igt_display_get_n_pipes() usage in main

The fixture won't be run when listing the subtests and thus we can't use
igt_display_get_n_pipes() in the list of tests. The alternative here is
to list the subtests with the maximum values and skip when not supported
on the platform.
