[DevVLVP] MBZ. This bit is the same as bit 19:18 in 61100h
[DevCDV, DevCTG, DevBW, DevCL, DevBLC] CRT Hot plug Voltage Compare Value:
Compare value for CRT hotplug detect Vref to determine whether the analog port is
connected to a CRT. The voltage is forced at the beginning of the active region of the
screen every 2 seconds.
00 = A0,
01 = B0, (Default)
10 = C0

[DevVLVP] MBZ. This bit is the same as bit 20 in 61100h
[DevCDV, DevCTG, DevBW, DevCL, DevBLC] CRT Hot Plug Detect Delay: This bit
determines the length of time between polling periods when the DAC/pipe are disabled
0 = 1G cdclks (default)
1 = 2G cdclks

[DevCDV, DevCTG, DevBW, DevCL, DevBLC] Force CRT detect trigger: Triggers a CRT
hotplug/unplug detection cycle independent of the interrupt enable bit. Bits 5:8 of this
register must be correctly programmed when forcing a trigger. This bit is automatically
cleared after the detection is completed. The result of this trigger is reflected in bits 9:8
of the port hotplug interrupt status register. The CRT interrupt status bit #11 in the hot
plug status register (61114) will get set the first time Force CRC detect trigger is used
after reset. Software must reset status after a force CRT detect trigger.
0 = No trigger (Default)
1 = Trigger

[DevCTG-B] CRT DAC hot plug detection reference voltage selection:
0 = 325mv, bits[6:5] should be set to 01 (Default)
1 = 475mv, bits[6:5] should be set to 11
