There is now support for the multiport USB controller this uses so
enable it.

The board only has a single port hooked up (despite it being wired up to
the multiport IP on the SoC). There's also a USB 2.0 mux hooked up,
which by default on boot is selected to mux properly. Grab the gpio
controlling that and ensure it stays in the right position so USB 2.0
continues to be routed from the external port to the SoC.

Hi Konrad,

   Sure, will add a default value for drive-strength for this pinctrl node.

Hi Andrew Halaney,

  I currently don't have a Ride device with me to test this change. Can 
you help test this patch on SA8540-Ride including (drive-strength = 
<2>;) property (which I believe is the default value).

I can test the same on SA8295-ADP and can push the next version quickly.

Regards,
Krishna,

nit I just noticed: s/sa8540-ride/sa8540p-ride/
please during the next spin!

The patch here for sa8540p-ride already includes the drive strength. I
did pull this on top of usb-next and it is working well for me in a
quick sanity test. Konrad's pinctrl-names/pinctrl-0 swap is purely
cosmetic of course, but for what is worth that works fine too.

I'd add my Tested-by for this patch, but it seems silly since I authored
the original :)

Also, make CHECK_DTBS=y qcom/sa8540p-ride.dtb is still reporting issues,
but other reviewers have highlighted that I believe. Just for the record
though, make sure you get those silenced!

I look forward to the next revision.

Thanks,
Andrew
