drm/i915/dp: Program vswing, pre-emphasis, test-pattern
This patch process phy compliance request by programming requested
vswing, pre-emphasis and test pattern.
v1: Initial patch.
v2: Fixes added during testing with test-scope. (Khaled/Clint/Manasi)
- pipe used as argument during registers programming instead of port.
- TRANS_CONF must be disable/enable as well during ddi disable/enable.
- harcoded PLTPAT 80 bit custom pattern as the DPR-100 does not set it
in the sink’s DPCDs
- TRANS_DDI_FUNC_CTL DDI_Select (Bits 27:30) need to reset/set during
disable/enable.
v3: used macros instead of numbers and some cosmetic changes. [Manasi]
