According to DP spec (2.9.3.1 of DP 1.4) if
EXTENDED_RECEIVER_CAPABILITY_FIELD_PRESENT is set the addresses in DPCD
02200h through 0220Fh shall contain the DPRX's true capability. These
values will match 0h through Fh, except for DPCD_REV,
MAX_LINK_RATE, DOWN_STREAM_PORT
From: Matt Atwood
This bit was added to DP Training Aux RD interval with DP 1.3. Via
descriptiion of the spec this field indicates the panels true
capabilities are described in DPCD address space 02200h through 022FFh.
