uniphier: make sure to create build directory before ROT key

Building the UniPhier platform in parallel with TRUSTED_BOARD_BOOT=1
could fail due to non-existing directory.  It might be difficult to
reproduce, but here is an easier way to trigger the problem:

$ make PLAT=uniphier TRUSTED_BOARD_BOOT=1 MBEDTLS_DIR=mbedtls certificates
  OPENSSL build/uniphier/release/rot_key.pem
/bin/sh: 1: cannot create build/uniphier/release/rot_key.pem: Directory nonexistent
make: *** [build/uniphier/release/rot_key.pem] Error 2

The $(ROT_KEY) must depend on $(BUILD_PLAT) so that the build directory
is created before the key.
