usb: gadget: mv_udc: refine the driver structure
This patch do the following things: 1. Add header and Copyright for marvell usb driver. 2. Add mv_usb.h in include/linux/platform_data, make the driver fits all the marvell platform using the same ChipIdea usb ip. 3. Some SOC may has mutiple clock sources, so let me define it in mv_usb_platform_data and give two helper functions named udc_clock_enable/udc_clock_disable to deal with the clocks. 4. Different SOCs will have some difference in PHY initialization, so we will remove file mv_udc_phy.c and add two funtions in mv_usb_platform_data, let the platform relative driver to realize it. 5. Rewrite probe function according to the modification list above. Find it will kernel panic when probe failed. The root cause is as follows: When probe failed, the error handle may call device_unregister() which in return will call gadget_release.In current code, gadget_release have two issues: 1: the_controller is a NULL pointer. 2: if we free udc here, then the following code in probe will access NULL pointer.
