reset: amlogic: move drivers to a dedicated directory

The meson reset driver will be split in two part, one implemeting the ops,
the other providing the platform driver support. This will be done to
facilitate the addition of the auxiliary bus support.

To avoid making a mess in drivers/reset/ while doing so, move the amlogic
reset drivers to a dedicated directory.
