usb: gadget: add a new rockusb gadget driver

This patch add a new rockusb gadget driver function.

For the design, simply embeding rockusb code into USB Mass Storage
function as using UMS framework can prominently improve upgrade speed
and devices stability.

This change does not affect the original USB Mass Storage function,
the rockusb process are just checked by IS_RKUSB_UMS_DNL macro which
only run when CONFIG_CMD_ROCKUSB was defined and rkusb_ums_dnl
composite driver was registed.

Use 'struct' instead of a typdef. Also since 'struct block_dev_desc' is long

ums: support multiple LUNs at once

Extend the ums command to accept a list of block devices. Each of these
will be exported as a separate LUN. An example use-case would be:

ums 0 mmc 0,0.1,0.2

... which would export LUNs for eMMC 0's user data, boot0, and boot1 HW
partitions. This is useful since it allows the host access to everything
on the eMMC without having to somehow stop the ums command from executing
and restart it with different parameters.

The concept of a single global offset/number of sectors to expose through
USB Mass Storage doesn't even make sense in the face of multiple storage
devices. Remove these defines to simplify the code.

usb: ums: code refactoring to improve reusability on other boards.

This patch introduces some cleanups to ums code. Changes:

ums common:
- introduce UMS_START_SECTOR and UMS_NUM_SECTORS as defined in
usb_mass_storage.h both default values as 0 if board config
doesn't define them

common cleanup changes:
- change name of struct "ums_board_info" to "ums"
- "ums_device" fields are moved to struct ums and "dev_num" is removed
- change function name: board_ums_init to ums_init
- remove "extern" prefixes from usb_mass_storage.h

cmd_usb_mass_storage:
- change error() to printf() if need to print info message
- change return values to command_ret_t type at ums command code
- add command usage string

Changes v2:
ums common:
- always returns number of read/write sectors
- coding style clean-up
ums gadget:
- calculate amount of read/write from device returned value.

usb:g_dnl:ums: Conditional compilation for mass storage function (f_mass_storage)

The mass storage composite function is now compiled in only when
CONFIG_USB_GADGET_MASS_STORAGE is defined.
Such change provides binary size reduction for boards which use USB
download gadget (like am335x_evm) with DFU, but don't use UMS.

For example at am335x_evm board reduction is more than 2KiB for
text and around 120B for data.
