tests/kms_plane_scaling: Fix mode selection for 2x tests
This patch will find the connector/mode combination that fits
into the bandwidth when more than one monitor is connected.
Example:
When two monitors connected through MST, the second monitor
also tries to use the same mode. So two such modes may not
fit into the link bandwidth. So, iterate through connected
outputs & modes and find a combination of modes those fit
into the link BW.
V2:
