IOSF_SB message space is used to access registers mapped
on IOSF-SB. These registers include uncore CRs (configuration
registers) and chipset specific registers. The Private
Configuration Register (PCR) space is accessed on IOSF-SB
using destination ID also known as Port ID.
Access to IOSF-SB by the Host or System Agent is possible
over PSF via the Primary to Sideband Bridge (P2SB). P2SB will
forward properly formatted register access requests as CRRd and

* `Configs_Type` became `Pipe_Configs`, `Config_Index` `Pipe_Index`.
Other noteworthy changes in libgfxinit:
* libgfxinit now knows about ports that share pins (e.g. HDMI1 and

(which is physically possible on certain ThinkPad docks).
* Major refactoring of the high-level GMA code.
