SDIO slave DAT pin is unfortunately the same pin as MTDI, which

controls the flash power voltage. For 3.3v flash devkits / modules /

kits, it conflicts with the DAT2 pullups required by the

specification.

This disables the peripheral input from the DAT2 so that we can work

in 1-bit mode when DAT2 is floating (pulled down). 4-bit mode is

therefore unavailable.
