This adds mx53 as the next user of the usbmisc driver and makes it
possible to disable the overcurrent-detection of the internal phy.

As every SoC platform's non-core register mapping is different,
it is better to use .h to put register bit definition
AFAIK in the kernel we don't make extra .h files any more, if there is
only a single user of the contents.
OK, if it is the current rule for kernel, then just keep it.
My original mind was there will be more and more bit definition
in future, and move it to .h to make the code clean and short.
