rockchip: Clean up parent directory creation for M0

The dependencies in the M0 Makefile are not correctly laid out, which
may lead to errors with make -j if the binary target gets evaluated
before the target that creates the directory. In addition, the M0
Makefile just calls mkdir without using the platform-independent macros
from the main ARM TF build system. This patch fixes those issues,
removes some unused (and broken) M0 build targets and merges the two M0
output directories into one (since there's no real point splitting it up
and it creates more hassle).

Therefore, we can remove the unused codes which copying explicitly
