We need to add a new sanity checks and also do
some preparations for adding ultrajoiner hw state readout.
Lets first split reading of the uncompressed joiner and bigjoiner
bit masks into separate functions.
v2: Fixed checkpatch warnings (Ankit)
v3: Use struct intel_display in the new functions. (Ankit)
v4: Use check for bigjoiner before reading the regs. (Ville)
