Remove sp_min functions from plat_common.c

This patch removes default platform implementations of sp_min
platform APIs from plat/common/aarch32/plat_common.c. The APIs
are now implemented in `plat_sp_min_common.c` file within the
same folder.

The ARM platform layer had a weak definition of sp_min_platform_setup2()
which conflicted with the weak definition in the common file. Hence this
patch fixes that by introducing a `plat_arm_` version of the API thus
allowing individual boards within ARM platforms to override it if they
wish to.

Fixes ARM-software/tf-issues#559
