fix: a3700: Fix the issue of make distclean

Armada37x0's ATF compilation includes native ATF code and
external WTP component. Thus, WTP component should also
be cleaned up along with ATF. However, WTP path is now
tied to DOIMAGEPATH, which is different from the default
for other Marvell SoCs. Thus, PLAT option is required in
order to clean up the WTP component:

    make PLAT=a3700 WTP=<path/to/wtp> distclean/clean

ATF always invokes make clean for "CRTTOOLPATH". When
specifying PLAT option in "make clean" command, it will
validate the "include" folder under "PLAT_DIR", which
expects "include" folder located in the same directory
of "platform.mk". Since the existing Armada37x0's PLAT
directory doesn't compiles with ATF convention, it caused
the error in "make clean".

The temporary solution is to add a symbolic link named as
'include' under "PLAT_DIR", which points to itself. This
WA will be removed after 'plat/marvell/a3700' folder is
reorganized.
