MdeModulePkg: Add PciSioSerialDxe driver
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.
(Sync patch r19179 from main trunk.)
