Proxy: Don't include platform_multicore.h

There are two versions of platform_multicore.h in the TF-M
source, both under platform/ext/target/... Partition code
should not be including header files from the platform directory
except where such header files are part of the platform API
(such as region_defs.h).

It seems in this case that the code doesn't actually need the #include,
so just remove it.
