Subject: [edk2-devel] [edk2-platforms][PATCH V1 1/1] ClevoOpenBoardPkg/N1xxWU: Enable continous mode Serial IRQ

REF:https://bugzilla.tianocore.org/show_bug.cgi?id=2068

This change sets the serial IRQ mode to continuous to allow the PS/2 keyboard and mouse to function properly in the OS. In the UEFI boot environment, the device uses a polling model so this change is not strictly required for that environment.
