msm: sps: Make DESC_FULL_ADDR(flags, addr) provide a phys_addr_t result
By convention, both the 'flags' and 'addr' arguments passed to
DESC_FULL_ADDR() come from struct sps_iovec, and so neither of
these values are 64 bit types. To guarantee that the result of
DESC_FULL_ADDR() is large enough to contain at 64bit address,
add an explicit phys_addr_t cast inside the macro.
