PaytonX Hsieh 23c71536ef UefiPayloadPkg: Fix issues when MULTIPLE_DEBUG_PORT_SUPPORT is true 
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4427

1. Since UART speed is slower than CPU, BIOS need to check the write
   buffer is empty, to avoid overwrite the buffer content.
2. LPSS UART might disable MMIO space for Windows debug usage during
   ExitBootServices event. BIOS need to avoid access the MMIO space
   after ExitBootServices.

Kavya 6937fc8338 UefiPayloadPkg/SerialPortLib: Enhance multi port behaviour 
Add condition to return success if mUartCount is greater
than zero in SerialPortInitialize() to avoid filling mUartInfo
with the same hob data when SerialPortInitialize() is called
multiple times. Also add proper conditions in SerialPortRead
function to read the data properly from multiple UART's.
