[igt-dev] [PATCH i-g-t 1/3] test/kms_chamelium: Start with disabling modeset

[Arkadiusz Hiler]

Doing disabling modeset from igt_display_require() is quite tricky, as
there are some tests that depend on the leftover mode set by fbcon in
order to work + PSR debugfs checks seem to behave a bit weird.

While those issues are being worked on let's do a disabling modeset
between igt_display_require() and chamelium_init() so port
auto-discovery works reliably on all configurations.
