ASoC: SOF: Intel: Add a is_amp flag to fix the wrong name prefix

According to the Intel sof design, it will create the name prefix
appended with amp index for the amp codec only, such as:
rt1318-1, rt1318-2, etc...

But the rt1320 is a codec with amp and mic codec functions, it doesn't
have the amp index in its name prefix as above.
And then it will be hard to identify the codec if in multi-rt1320 case.
So we add a flag to force the amp index to be appended.
