mediatek: bpi-r64: use dt-overlay to select SATA or PCIE1
The Bananapi BPi-R64 got a SATA interface which cannot be used at the
same time as the second mPCIe slot. The decission is made by hogging
GPIO 90.
Embed two addtional DT overlay blobs into the image to allow bootloader
selection of either SATA or PCIE1 feature.
