mainboard: Add Sapphire Pure Platinum H61

This board has a socketed SOIC-8 4 MB flash chip. All the flash
regions are unlocked by default but unfortunately flashrom
doesn't work with the original firmware and the stock UEFI flash
tool refuses to flash the coreboot image (different image ID).
For now, the external programmer seems to be the only option for
the first coreboot flashing.

Tested and working:
 * Debian GNU/Linux Stretch (with Linux kernel 4.9, SeaBIOS)
 * Microsoft Windows 7 installer with VGA blob (SeaBIOS)
 * Internal GPU, both with VGA blob and libgfxinit (VGA and DVI)
 * External GPU
 * RAM (tested 8 + 8 GB)
 * S3
 * USB, both the 2.0 and 3.0 ports
 * Sata
 * Thermal management
 * Sound
 * LAN
 * Bluetooth
 * VT-x and VT-d
 * me_cleaner

Not working:
 * Microsoft Windows 7 installer with libgfxinit

Untested:
 * Backside Mini PCI-E port
 * DisplayPort and HDMI ports

Issues:
 * The USB is always powered, even is S3 and S5 (like in the
    original firmware).
 * Internal flashing with flashrom doesn't work after resuming
    from S3.
 * The raminit is unreliable, as the RAM training sometimes fails
    and sometimes succeeds, with the same couple of RAMs. Once
    a MRC cache has been created, the raminit works fine.
 * If an external card is inserted and the option
    ONBOARD_VGA_IS_PRIMARY is not enabled, the internal GPU
    disappears completely from the PCI bus.
