I did test with VMSPLIT_2G today, the mmc/sd controller will not work
anymore on rpi4 boards, so enable VMSPLIT_2G is not a solution so far.
And today I also tested dwc2, it worked well, maybe we could enable dwc2
instead of dwc_otg, then we could use a single kernel to support
rpi2/3/4. dwc2 work
These are the kernels with the dwc2 enabled (replaced dwc_otg with dwc2
for both arm64 and armhf kernels).
