MdeModulePkg: Add PciSioSerialDxe driver

Browse Source 
PciSioSerialDxe driver can manages UARTs on a SIO chip or a PCI/PCIE
card.
It manages the SIO instance whose last device path node is a ACPI
device path and the HID in the ACPI device path node equals to
EISA_PNP_ID (0x501).
It also manages the PCI IO instance whose class code is 7/0/2 (16550
UART). But when proper value is set to PcdPciSerialParameters, the
driver can also manage non-standard PCI serial cards by matching
the Vendor ID and Device ID specified in PcdPciSerialParameters.
The PCI BAR index, IO/MMIO offset, register stride, clock rate can
also be specified through the same PCD.

## PCI Serial Parameters. It is an array of VendorID, DeviceID, ClockRate, Offset,
# BarIndex, RegisterStride, ReceiveFifoDepth, TransmitFifoDepth information that
# describes the parameters of special PCI serial devices.
# Each array entry is 24-byte in length. The array is terminated
# by an array entry with a PCI Vendor ID of 0xFFFF. If a platform only contains a
# standard 16550 PCI serial device whose class code is 7/0/2, the value is 0xFFFF.
# The C style structure is defined as below:
# typedef struct {
# UINT16 VendorId; ///< Vendor ID to match the PCI device. The value 0xFFFF terminates the list of entries.
# UINT16 DeviceId; ///< Device ID to match the PCI device
# UINT32 ClockRate; ///< UART clock rate. Set to 0 for default clock rate of 1843200 Hz
# UINT64 Offset; ///< The byte offset into to the BAR
# UINT8 BarIndex; ///< Which BAR to get the UART base address
# UINT8 RegisterStride; ///< UART register stride in bytes. Set to 0 for default register stride of 1 byte.
# UINT16 ReceiveFifoDepth; ///< UART receive FIFO depth in bytes. Set to 0 for a default FIFO depth of 16 bytes.
# UINT16 TransmitFifoDepth; ///< UART transmit FIFO depth in bytes. Set to 0 for a default FIFO depth of 16 bytes.

# } PCI_SERIAL_PARAMETER;
# It contains zero or more instances of the above structure.
# For example, if a PCI device contains two UARTs, PcdPciSerialParameters needs
# to contain two instances of the above structure, with the VendorId and DeviceId
# equals to the Device ID and Vendor ID of the device; If the PCI device uses the
# first two BARs to support two UARTs, BarIndex of first instance equals to 0 and
# BarIndex of second one equals to 1; If the PCI device uses the first BAR to
# support both UARTs, BarIndex of both instance equals to 0, Offset of first
# instance equals to 0 and Offset of second one equals to a value bigger than or
# equal to 8.
# For certain UART whose register needs to be accessed in DWORD aligned address,
# RegisterStride equals to 4.
