This series picks up a few patches from the TI BSP tree that
unfortunately didn't make it upstream thusfar.

The first patch improve SD card compatibility (allowing U1 class cards
to be used), the remaining ones add USB support.

The type-c connector isn't entirely modelled with these changes as
it goes through a TPS6598 PD controller. Unfortunately the dtb bindings
for that currently require an irq line, which is not connected on E1 and
E2 version boards. The patchese to support this setup unfortunately didn't land
yet[0].. As such the last patch ignored the PD controller and simply
configures usb0 as periphal only rather then mode switch capable, which
at least gives some basic usability of that USB port.
