Let's set up musb-dsps with a custom read_fifo function based on the compatible flag. Otherwise we can get the following errors when starting dhclient on a asix USB Ethernet adapter: asix 2-1:1.0 eth2: asix_rx_fixup() Bad Header Length 0xffff003c, offset 4 While at it, let's also remove pointless cast of the driver data.

However, sometimes usbhsg_queue_pop() function is called with interrupts enabled. So, this function should be held by usbhs_lock() to disable interruption. Also, this driver has to call spin_unlock() to avoid spinlock recursion by this driver before calling usb_gadget_giveback_request(). Otherwise, there is possible to cause a spinlock suspected in a gadget complete function.
