SDIO is not supported in u-boot, there is no point in enabling mmc3.
For this purpose, add u-boot specific dtsi that this will be included
automatically while building the dtb.

The intention of having a -u-boot.dtsi file is to be able to make
changes to the provided upstream dts files as well as to be able to add
nodes.  Change the logic for adding the file from making it the last
included file at the top of the dts to being included at the end of the
file.

Move the Gen5 specific code to _gen5 files.

- Change all uint32_t to u32 and change to use macro BIT(n) for bit shift.
- Check return value from wait_for_bit(). So change return type to int for
  cm_write_with_phase() and cm_basic_init().

Each time set_state is called, a new piece memory will
be allocated for pin_data, but not freed, this will
incur memory leak.

When error, the devm API could not free memory automatically.
So need call devm_kfree when error.

Early backports of the imx wdog external reset feature occured before the

'fsl,ext-reset-output'. In order to support older kernels remove both
