OvmfPkg/LsiScsiDxe: Open PciIo protocol and initialize the device

Browse Source 
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()
