Backend driver for MUSB OTG controllers found on TI AM35x. It seems that on AM35X interrupt status registers can be updated _before_ core registers. As we don't use true interrupts in U-Boot and poll interrupt status registers instead this can result in interrupt handler being called with non-updated core registers. This confuses the code and result in hanged transfers. Add a small delay in am35x_interrupt as a workaround. Signed-off-by: Ilya Yanok <ilya.yanok@cogentembedded.com>
