At present the vendor storage partition is small than 64K in the
design, so vendor storage r/w commands do not take multi-packet
into consideration, if it is needed, the codes should do a little
change in future. Besides, the RPMB r/w support need to be added
when its APIs get ready.

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.
