The class device only handles descriptor information specific to the class,
and shared descriptor information is passed through parameters and
handled by the composite driver.

A usbdev has only one serial string, so use a unique macro to control it.
For boards that enable board serial string using COMPOSITE_BOARD_SERIALSTR,
PL2303_BOARD_SERIALSTR, CDCACM_BOARD_SERIALSTR, USBADB_BOARD_SERIALSTR,
USBMSC_BOARD_SERIALSTR, and RNDIS_BOARD_SERIALSTR, they need to be replaced
with BOARD_USBDEV_SERIALSTR.

unbind will call the adb_char_on_connect interface to wake up the adbd task,
adbd will then access the adb device and fail to return, at this time it will
close the adb device, we can do the final memory release operation in the
second unbind

since mmap may exist in block_operations, but truncate may not,
moving mmap beforee truncate could make three struct more compatible

- Add mmap into file_operations and remove it from ioctl definitions.
- Add mm_map structure definitions to support future unmapping
- Modify all drivers to initialize the operations struct accordingly

iSerialNumber field in the device descriptor can be used to determining the
board when multiple boards connected to the same host. So add feature to change
serial string by board unique ID dynamically.
To use this feature, user must be implement the board_usbdev_serialstr() logic.
