tests: Add test for pipe B and C interactions in IVB
The tests exercise different combinations of enabling pipe B with modes
that require more than 2 lanes and then enabling pipe C.
v2: Added a couple more tests for different pipe transitions. (Ander)
Use custom modes to make the test reliable. (Daniel)
v3: Add IGT_TEST_DESCRIPTION. (Thomas)
Rename test to kms_pipe_b_c_ivb. (Ander)
v4: Fix subtest enumeration. (Thomas)
