usb: dwc3: fix few coding style problems

There were a few coding style issues with this driver
which are now fixed:

	<linux/uaccess.h> instead of <asm/uaccess.h>
drivers/usb/dwc3/debugfs.c:484: ERROR: space required \
	before the open brace '{'
drivers/usb/dwc3/ep0.c:261: WARNING: line over 80 characters

	for conditional statements (16, 23)

drivers/usb/dwc3/io.h:42: WARNING: Use #include \
	<linux/io.h> instead of <asm/io.h>
