mb/gigabyte: add GA-P67A-UD3R

This is a Intel P67 chipset motherboard for Sandy Bridge processors.
The P67 chipset has no graphics support.

This board has redundant 4MB SOIC-8 flash chips, and the flashrom internal
programmer is usable with the vendor BIOS.

This is an original P67 chipset, and is affected by a SATA 2 hardware bug.
There is a variant P67A-UD3R-B3, that is the same board with a B3
stepping chipset that fixes this bug.

The function of PCI Express ports PCIEX4 and PCIEX1_* are configured in
PCHSTRP9. By default, PCIEX4 is configured for 4 lanes and PCIEX1_* are
disabled. This can be switched to 1 lane for all ports.

This port was created with the help of autoport and other GIGABYTE ports.

Tested and working:
 - Intel Core i5-2500/i7-2600
 - 4 DIMMs (4x4GB DDR3-1333) with native RAM init
 - Booting Linux 4.19 from SeaBIOS (SATA and USB)
 - PCI Express graphics
 - Onboard Ethernet
 - Sensors (SuperIO)
 - S3 sleep
 - SATA 3
 - USB 2.0
 - USB 3.0 (NEC xHCI)
 - Onboard audio (speakers, headphones)
 - CMOS
 - EHCI debug port
 - Serial port
 - Conventional PCI (only with one card)
 - PS/2 keyboard

Not tested:
 - SATA 2 (hardware bug)
 - PS/2 mouse
 - Digital audio
