board: ge: b1x5v2: Add GE B1x5v2 and B1x5Pv2

GE B1x5v2 patient monitor series is similar to the CARESCAPE Monitor
series (GE Bx50). It consists of a carrier PCB used in combination
with a Congatec QMX6 SoM. This adds U-Boot support using device model
everywhere and SPL for memory initialization.

Proper configuration is provided as 'ge_b1x5v2_defconfig' and the
combined image u-boot-with-spi.imx can be flashed directly to 1024
byte offset to /dev/mtdblock0. Alternatively SPL and u-boot.imx can
be loaded separately via USB-OTG using e.g. imx_usb.
