MdePkg: Handle Sata device path when optional para is not specified
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1243
Sata device path format:Sata(HPN, PMPN, LUN)
According to UEFI Spec, the PMPN is an integer between
0 and 65535 and is optional. If not provided, the default is 0xFFFF.
This commit is to do the enhancement for Sata device path
when optional para is not specified.
