fw_env: use env-size property for nvmem layout device detection

Since Linux commit 5b2f8c133d98 ("nvmem: layouts: u-boot-env:
add optional "env-size" property"), there is support for providing the size
of the u-boot environment used by the bootloader to the layout NVMEM driver
in order to calculate the CRC if the range is less than the partition size
in a similar fashion that it would be provided in a fw_env.config file.

Devicetree binary cells are always stored in big-endian,
so endian translation is now necessary for this case.

Reuse the buffer that holds the path for opening the compatible sysfs file
for parsing this env-size property and possibly more in the future,
as soon as the correct device is identified with the compatible property.
