This commit renames the “speed” field of the usb_gadget_driver structure to “max_speed”. This is so that to make it more apparent that the field represents the maximum speed gadget driver can support. This also make the field look more like fields with the same name in usb_gadget and usb_composite_driver structures. All of those represent the *maximal* speed given entity supports. After this commit, there are the following fields in various structures: * usb_gadget::speed - the current connection speed, * usb_gadget::max_speed - maximal speed UDC supports, * usb_gadget_driver::max_speed - maximal speed gadget driver supports, and * usb_composite_driver::max_speed - maximal speed composite gadget supports.

Several UDC drivers had a gadget driver's speed sanity check of the form of: driver->speed != USB_SPEED_HIGH or: driver->speed != USB_SPEED_HIGH && driver->speed != USB_SPEED_FULL As more and more gadget drivers support USB SuperSpeed, driver->speed may be set to USB_SPEED_SUPER and UDC driver should handle such gadget correctly. The above checks however fail to recognise USB_SPEED_SUPER as a valid speed. This commit changes the two checks to: driver->speed < USB_SPEED_HIGH or: driver->speed < USB_SPEED_FULL respectively.

In a few places in the kernel, the code prints a human-readable USB device speed (eg. "high speed"). This involves a switch statement sometimes wrapped around in ({ ... }) block leading to code repetition. To mitigate this issue, this commit introduces usb_speed_string() function, which returns a human-readable name of provided speed. It also changes a few places switch was used to use this new function. This changes a bit the way the speed is printed in few instances at the same time standardising it.

Add support for the dedicated FIFO mode on newer SoCs such as the S5PV210 partly to improve support and to fix the bug where any non-EP0 IN endpoint requires its own FIFO allocation. To fix this, we ensure that any non-zero IN endpoint is given a TXFIFO using the same allocation method as the periodic case (all our current hardware has enough FIFOs and FIFO memory for a 1:1 mapping) and ensure that the necessary transmission done interrupt is enabled. The default settings from reset for the core point all EPs at FIFO0, used for the control endpoint. However, the controller documentation states that all IN endpoints _must_ have a unique FIFO to avoid any contention during transmission. Note, this leaves us with a large IN FIFO for EP0 (which re-uses the old NPTXFIFO) for an endpoint which cannot shift more than a pair of packets at a time... this is a waste, but it looks like we cannot re-allocate space to the individual IN FIFOs as they are already maxed out (to be confirmed).

Up the FIFO size for the TX to 1024 entries, as this now seems to work with all the cores. This fixes a problem when using large packets on a core with MPS set to 512 can hang due to insufficient space for the writes. The hang arises due to getting the non-periodic FIFO empty IRQ but not being able to satisfy any requests since there is never enough space to write 512 bytes into the buffer. This means we end up with a stream of interrupt requests. It is easier to up the TX FIFO to fill the space we left for it than to try and fix the positions in the code where we should have limited the max-packet size to < TXFIFOSIZE, since the TXFIFOSIZE depends on how the TX FIFOs have been setup.
