OvmfPkg/LsiScsiDxe: Open PciIo protocol and initialize the device
Open PciIo protocol and use it to initialize the device. The
initialization of LSI 53C895A is simple: just set the SRST bit in
Interrupt Status Zero register to reset the device.
v2:
- Use the BITx macros for the bit constants
- Add the closing of PciIo protocol in LsiScsiControllerStop()
