mb/asrock: Add Z87E-ITX (Haswell)

This was done using Haswell autoport, with manual fixes to get the
output to build against current main. I do not physically have this
board; I was sent the output of autoport with some fixes on top of
which I added additional changes. The VBT was copied from
/sys/kernel/debug/dri/0/i915_vbt on version 2.70 of the vendor firmware.

The flash chip is 8MiB in a socketed DIP8 package, making it easy to
externally flash to recover from a brick.

Working:
- Haswell MRC.bin
- S3 suspend and resume
- Libgfxinit
- HDMI
- DVI-I (including passive DVI to VGA adapter)
- DisplayPort
- SATA ports
- mSATA SSD
- mPCIe WiFi slot
- Rear USB ports
- USB 3.0 header
- Audio header
- Ethernet
- x16 PCIe slot
- EHCI debug with the CH347 (top USB 2.0 port by the PS/2 connector)
- edk2 (MrChromebox uefipayload_202309)

Not Tested:
- PS/2 keyboard/mouse
- eSATA
- USB 2.0 header
