usb: gadget: UMS: support multiple sector sizes
UFS storage often uses a 4096-byte sector size, add support for dynamic
sector sizes based loosely on the Linux implementation.
Support for dynamic sector sizes changes the types used in some
divisions, resulting in the compiler attempting to use
libgcc helpers (__aeabi_ldivmod).
Replace these divisions with calls to lldiv() to handle this correctly.
