DynamicTablesPkg: Fix parsing of serial port node

When scanning for the Serial Port in the device
tree, the length and value parameters to ScanMem8()
are not in the right order. This results in the
serial port not being detected if the chosen node
in the device tree has additional elements.

Therefore, pass the parameters to ScanMem8() in the
correct order to fix this issue.
