Commit 05ee799f2021 ("usb: dwc2: Move gadget settings into core_params")
changes to type u16 for DT binding "g-rx-fifo-size" and
"g-np-tx-fifo-size" but use type u32 for "g-tx-fifo-size". Finally the
the first two parameters cannot be passed successfully with wrong data
format. This is found the data transferring broken on 96boards Hikey.

This patch is to change all parameters to u32 type, and verified on
Hikey board the DT parameters can pass successfully.

Nice!

This patch (while it doesn't apply cleanly to v4.10-rc2) does resolve
the regression I reported earlier here:
https://www.spinics.net/lists/linux-usb/msg150766.html

I didn't see the slight shift to u16s there.

Leo, does the patch need a respin, or is it against Linus' HEAD and my
tree is stale?

Anyway, after re-applying it to my tree:

Thanks Leo and John.

I just sent out a rebased version for Felipe to pick up.

Yeah, I should respin it.
