UPSTREAM: usb: composite: Move bitmap related operations to ./include/linux/bitmap.h

The BITMAP related operations can now be moved to ./include/linux/bitmap.h
file to mimic the Linux kernel directory tree.

This change also allows to remove the lin_gadget_compat.h header file
(which is a legacy code only for composite U-boot layer).
It was also possible to remove #includes from several USB gadget drivers.

treewide: replace with error() with pr_err()

U-Boot widely uses error() as a bit noisier variant of printf().

This macro causes name conflict with the following line in
include/linux/compiler-gcc.h:

# define __compiletime_error(message) __attribute__((error(message)))

This prevents us from using __compiletime_error(), and makes it
difficult to fully sync BUILD_BUG macros with Linux. (Notice
Linux's BUILD_BUG_ON_MSG is implemented by using compiletime_assert().)

Let's convert error() into now treewide-available pr_err().

Done with the help of Coccinelle, excluing tools/ directory.

The semantic patch I used is as follows:

// <smpl>
@@@@
-error
+pr_err
(...)
// </smpl>

usb: modify usb_gadget_handle_interrupts to take controller index

Since we support multiple dwc3 controllers to be existent at the same
time, in order to handle the interrupts of a particular dwc3 controller
usb_gadget_handle_interrutps should take controller index as an
argument.

Hence the API of usb_gadget_handle_interrupts is modified to take
controller index as an argument and made the corresponding changes to all
the usb_gadget_handle_interrupts calls.

USB: gadget: atmel_usba_udc: fix transfer hang issue

When receive data, the RXRDY in status register set by hardware
after a new packet has been stored in the endpoint FIFO. After,
we copy from FIFO, we clear it, make the FIFO can be accessed
again.
In the receive_data() function, this bit RXRDY has been cleared.
So, after the receive_data() function return, this bit should
not be cleared again, or else it will cause the accessing FIFO
corrupt, which will make the data loss.

USB: gadget: atmel: zero out allocated requests

A UDC's alloc_request method should zero out the newly allocated request.
Ensure the Atmel driver does so. This issue was found by code inspection,
following the investigation of an intermittent issue with ci_udc, which
was tracked down to failing to zero out allocated requests following some
of my changes. All other UDC drivers already zero out requests in one
way or another.
