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.
