The ROC-RK3399-PC has an MP8859 regulator on I2C7 at address 0x66,
while the ROC-RK3399-PC-PLUS does not. Probe for the regulator in SPL
and use the result to select the matching devicetree from the U-Boot
FIT. Fall back to the original board if the I2C bus cannot be probed.
Build both devicetrees from the existing roc-pc-rk3399_defconfig and
enable the XMC SPI NOR driver used by the Plus variant. Set fdtfile
from the selected U-Boot devicetree so the matching Linux devicetree
is used as well.
