efi/libstub/arm: default EFI_ARMSTUB_DTB_LOADER to y 

Default EFI_ARMSTUB_DTB_LOADER to y to allow the dtb= command
line parameter to function with efi loader.

Required for development purposes and to boot on existing bootloaders
that do not support devicetree provided by the firmware or by the
bootloader.

Select this config option to add support for the dtb= command
line parameter, allowing a device tree blob to be loaded into
memory from the EFI System Partition by the stub.
The device tree is typically provided by the platform or by
the bootloader, so this option is mostly for development
purposes only.
If the device tree is provided by the platform or by
the bootloader this option may not be needed.
But, for various development reasons and to maintain existing
functionality for bootloaders that do not have such support
this option is necessary.
