  DEVDISRn registers provides a mechanism for gating clocks of IP blocks
  that are not used. Here we implement hwconfig option to allow users
  to disable unused peripherals on the board.

  For ex. If eSDHC/qDMA/eDMA are unused and with disabled status in dts,
  User can enable CONFIG_FSL_DEVICE_DISABLE and set "devdis:esdhc,qdma,edma"
  in hwconfig, thus ESDHC controller & eDMA/qDMA will be clock gated to
  save more power.
