Misra C required signed/unsigned conversion with cast.

V1->V2:
  a.split patch to patch series

V2->V3:
  a.Change the API tgt_uart/ static int uart16550_get_rx_err(uint32_t rx_data) to return uint32_t
  b.modified the format of if from "if (length > 32*(length/32))" to
"if (length % 32U > 0)"

V3->V4:
  a.change the uint64_t type numeric constant's suffix from U to UL
