[PATCH] usb: gadget: pxa25x_udc: use devm_ functions

This patch introduces the use of devm_request_irq, devm_gpio_request, devm_clk_get etc. instead of the corresponding unmanaged interfaces. The calls to the functions like free_irq to free the allocated resources are removed as they are no longer required. Some labels in the probe function are also
