kernel: generic: use chosen bootconf in FIT partition parser
If the selected boot configuration is stored by U-Boot in '/chosen'
node as 'bootconf' attribute, use that configuration to resolve the
block device used as rootfs. Fall back to use the default configuration
in case 'bootconf' is not present.
