ARM: config: USB: Tegra30/114: Fix EHCI timeout issue on "bootp"
Fix the timeout issue after running "bootp" command in u-boot
console. For example you see "EHCI timed out on TD- token=0x...".
TXFIFOTHRES bits of TXFILLTUNING register should be set to 0x10
after a controller reset and before RUN bit is set
(per technical reference manual).
