fix(plat/xilinx/zynqmp): use sync method for blocking calls
All API calls except non-blocking should wait for
IPI response and read buffer to check return status
from firmware. Some of API calls are not reading
status from IPI payload data. Use sync method which
reads actual return status from IPI payload.
