There is no PMC_TYPE_ because it refers to a different block external to 
the PMC block. PMC feeds the UTMI clock which feeds the UTMI block that 
contains the three UTMI clocks: the one for port A and the ones meant 
for port B and C which depend on port A's UTMI clock. There is no 
control in the PMC for these. The reason why I added UTMI in this file 
is because it is related to DT clock definitions.
