u-boot: Add support for custom make options
For some platforms (e.g. stm32mp1) the official way to build U-boot
with a device tree other than the board's default requires passing
additional make options such as DEVICE_TREE=xxx or EXT_DTB=xxx.
Instead of adding each possible option as a parameter in the .in
file, add a generic mechanism to allow passing custom make options
to U-boot. A similar approach has been adopted by buildroot.
