[PATCH v10 07/12] soc: mediatek: Remove infracfg misc driver support

From: Weiyi Lu
Date: Wed Dec 18 2019 - 03:31:24 EST

In previous patches, we introduce scpsys-ext driver that covers
the functions which infracfg misc driver provided.
And then replace bus_prot_mask with bp_table of all compatibles.
Now, we're going to remove infracfg misc drvier which is no longer
being used.
