GPT provides partition labels, which can be used to tell the kernel to find
the rootfs based on it (root=PARTLABEL=rootfs) as a nicer/more extensible
solution than the MBR disk signature / PARTUUID.
When using GPT, the name of the partition in genimage.cfg is used as the
label for that partition.
The default GPT partition table location unfortunately conflicts with the
SPL location, so move the 16KB GPT table after it.

The probing order of the two mmc controllers (sdcard and sdio wifi) has
changed in kernel 5.10 since commit 21b2cec61c04bd1 (mmc: Set
PROBE_PREFER_ASYNCHRONOUS for drivers that existed in v4.4), so change to
root=PARTUUID=.. instead of hardcoding /dev/mmcblkXp2.

Very similar to orangepi-zero, except that the board has a 16MB SPI flash, a
2nd ethernet port is provided through a Realtek RTL8152 and wifi is provided
through a Realtek RTL8189FTV (no mainline driver, not supported).
