This is done as part of iodelay configuration sequence and is required due to the limitations introduced by erratum ID: i869[1] and elaborated in the Technical Reference Manual[2] 18.4.6.1.7 Isolation Requirements. Only peripheral that is permitted for dynamic pin mux configuration is MMC. This is to accommodate the requirements for varied speeds (which require IO-delay support in kernel as well). Hence with the exception of MMC, all other pin mux configurations are removed from the dts.
