mb/asrock/b75m-itx: Add Sandy/Ivy Bridge board B75M-ITX

- two banks 4+4GB CL9
- two banks 8+8GB CL10

OS:
- Gentoo Linux LiveUSB, KDE desktop (Linux 5.15.72)

Working:
- GRUB2 payload with embedded default config for boot from USB, disk
- UEFI EDK2 payload
- Intel ME stripped
- Native raminit
- Integrated graphics with libgfxinit (HDMI, DVI and VGA)
- (boot from) SATA2, SATA3, ports
- Rear USB 2 and 3 ports (supports boot)
- Internal USB 3.0 ports
