add a field to the android_usb_platform_data structure to allow platforms
to specify the size of the bulk transfer buffer; if unspecified, default
to the BULK_BUFFER_SIZE defined by f_mass_storage.c (previously defined as
4KiB).

on harmony (tegra 2), performance of a class 10 SD card mounted
as USB mass storage through this gadget has been measured to increase
from ~7MB/sec read to ~17MB/sec read by increasing the buffer size
from 4KiB to 16KiB.
