pinmuxing for DRA7x/AM57x family of processors need to be done in IO

Only peripheral that is permitted for dynamic pin mux configuration is

Actually its MMC and DCAN. DCAN because of i893 ("DCAN Initialization
Sequence"). But I can see you may have omitted reference to it since
DCAN is not really used on the x15.
