trusty: Avoid signed overflow SMC_FC_FFA_MEM_FRAG_RX returns the 16 bit sender-id in the top 16 bits of 32 bit register. Cast to uint32_t before shifting it up to avoid having the uint16_t promoted to a signed int for the shift. Currently the value we return will never have the top bit of the sender-id in this context, but this could change in the future. Bug: 185307117 Change-Id: I401e3bcf9dbe2ffa99f03e527df0f9f3f8ff0d3e
