remove reference to the obsolete EFI_LIGHT_ISA_IO_PROTOCOL. This protocol is introduced for size reduction. But later this method is obsoleted as EDK II use feature flags to conditional mask off some code. As EDK II core code does not produce this protocol so we remove all reference to this protocol.

Routine Description:
Performs an ISA I/O Read/Write Cycle
EFI_LIGHT_ISA_IO_PROTOCOL doesn't verfiy access for I/O operation.
Arguments:
This - A pointer to the EFI_ISA_IO_PROTOCOL or EFI_LIGHT_ISA_IO_PROTOCOL instance.
Width - Signifies the width of the I/O operation.
Offset - The offset in ISA I/O space to start the I/O operation.
Count - The number of I/O operations to perform.
Buffer - The source/destination buffer
Returns:
EFI_SUCCESS - The data was read from or written to the device sucessfully.
EFI_UNSUPPORTED - The Offset is not valid for this device.
EFI_INVALID_PARAMETER - Width or Count, or both, were invalid.
EFI_OUT_OF_RESOURCES - The request could not be completed due to a lack of resources.

Routine Description:
Maps a memory region for DMA, EFI_LIGHT_ISA_IO_PROTOCOL only supports
Slave read/write operation to save code size.
Arguments:
This - A pointer to the EFI_LIGHT_ISA_IO_PROTOCOL instance.
Operation - Indicates the type of DMA (slave or bus master), and if
the DMA operation is going to read or write to system memory.
ChannelNumber - The slave channel number to use for this DMA operation.
If Operation and ChannelAttributes shows that this device
performs bus mastering DMA, then this field is ignored.
The legal range for this field is 0..7.
ChannelAttributes - The attributes of the DMA channel to use for this DMA operation
HostAddress - The system memory address to map to the device.
NumberOfBytes - On input the number of bytes to map. On output the number
of bytes that were mapped.
DeviceAddress - The resulting map address for the bus master device to use
to access the hosts HostAddress.
Mapping - A resulting value to pass to EFI_ISA_IO.Unmap().
Returns:
EFI_SUCCESS - The range was mapped for the returned NumberOfBytes.
EFI_INVALID_PARAMETER - The Operation or HostAddress is undefined.
EFI_UNSUPPORTED - The HostAddress can not be mapped as a common buffer.
EFI_DEVICE_ERROR - The system hardware could not map the requested address.
EFI_OUT_OF_RESOURCES - The memory pages could not be allocated.
