Burnside bridge retimer: Add Thunderbolt-compatible mode bits
Intel burnside bridge retimer supports the ability to train the
link and operate in both Thunderbolt 1/2(10Gbps) and Thunderbolt 3
(20Gbps) link speeds.
Adding the following fields in the configuration register
of the retimer to support Thunderbolt-compatible mode:
1. Active cable - Active/passive cable
2. Thunderbolt connection - Thunderbolt configured or not
3. Thunderbolt type - Type-C Type-C or Type-C legacy thunderbolt
adapter
4. Thunderbolt Cable type - Optical or Electrical
5. Active link training - Unidirectional or bidirectional link
training
6. Thunderbolt cable speed - 10Gbps/20Gbps active/passive cable
7. Thunderbolt Generation - 3rd generation or 4th generation
thunderbolt cable
BUG=b:140645327
BRANCH=None
TEST=Manually verified on Tglrvp-U, able to configure the registers
