x86: Add congatec conga-QA3/E3845-4G (Bay Trail) support

This patch adds support for the congatec conga-QA3/E3845-4G eMMC8 SoM,
installed on the congatec Qseven 2.0 evaluation carrier board
(conga-QEVAL).

Its port is very similar to the MinnowboardMAX port and also uses
the Intel FSP as described in doc/README.x86.

Currently supported are the following interfaces / devices:
- UART (via Winbond legacy SuperIO chip on carrier board)
- Ethernet (PCIe Intel I210 / E1000)
- SPI including SPI NOR as boot-device
- USB 2.0
- SATA via U-Boot SCSI IF
- eMMC
- Video (HDMI output @ 800x600)
- PCIe

Not supported yet is:
- I2C
- USB 3.0

This is the congatec Qseven 2.0 evaluation carrier board
(conga-QEVAL) equipped with the conga-QA3/E3845-4G SoM.
It contains an Atom E3845 with Ethernet, micro-SD, USB 2,
USB 3, SATA, serial console and HDMI 1.3 video out.
It requires some binary blobs - see README.x86 for details.
Note that PCIE_ECAM_BASE is set up by the FSP so the value used
by U-Boot matches that value.
