retimer: Add driver support for Intel Burnside Bridge retimer
Burnside Bridge is a Type-C multi-protocol retimer to be used in on-board
applications. Burnside Bridge offers the ability to latch protocol signals
into on-chip memory before retransmitting them onwards. It can be used to
extend the physical length of the system without increasing high frequency
jitter.
Burnside Bridge supports spec compliant retimer of following protocols:
1. Display Port: four unidirectional DP lanes
2. USB3.1 Gen1/2: one bi-directional USB lane
3. Thunderbolt: two bi-directional CIO lanes
4. Multifunction Display (MFD): two unidirectional lanes of DP and one
bi-directional lane of USB3.1 Gen1/2
Note: Only item 1, 2 & 4 are supported in this CL. Item 3 support will
be added in follow on CLs.
BUG=b:127623438
BRANCH=none
TEST=Manually verified on ICLRVP, able to configure the registers
