drm/client: Handle tiled displays better
When testing on my tiled display, initially the tiled display is
detected correctly:
[90376.523692] xe 0000:67:00.0: [drm:drm_client_firmware_config.isra.0 [drm]] fallback: Not all outputs enabled
[90376.523713] xe 0000:67:00.0: [drm:drm_client_firmware_config.isra.0 [drm]] Enabled: 0, detected: 2
...
[90376.523967] xe 0000:67:00.0: [drm:drm_client_modeset_probe [drm]] [CRTC:82:pipe A] desired mode 1920x2160 set (1920,0)
[90376.524020] xe 0000:67:00.0: [drm:drm_client_modeset_probe [drm]] [CRTC:134:pipe B] desired mode 1920x2160 set (0,0)
But then, when modes have been set:
[90379.729525] xe 0000:67:00.0: [drm:drm_client_firmware_config.isra.0 [drm]] [CONNECTOR:287:DP-4] on [CRTC:82:pipe A]: 1920x2160
[90379.729640] xe 0000:67:00.0: [drm:drm_client_firmware_config.isra.0 [drm]] [CONNECTOR:289:DP-5] on [CRTC:134:pipe B]: 1920x2160
...
[90379.730036] xe 0000:67:00.0: [drm:drm_client_modeset_probe [drm]] [CRTC:82:pipe A] desired mode 1920x2160 set (0,0)
[90379.730124] xe 0000:67:00.0: [drm:drm_client_modeset_probe [drm]] [CRTC:134:pipe B] desired mode 1920x2160 set (0,0)
Call drm_client_get_tile_offsets() in drm_client_firmware_config() as
well, to ensure that the offset is set correctly.
This has to be done as a separate pass, as the tile order may not be
equal to the drm connector order.
