Subject: [PATCH v4 2/5] amba: Only descend into amba directory when CONFIG_ARM_AMBA is set

From: "Andrew F. Davis" <[email-masked]>
Date: Tue, 5 Dec 2017 13:44:53 -0600

When CONFIG_ARM_AMBA is not set make will still descend into the amba
directory but nothing will be built. This produces unneeded build
artifacts and messages in addition to slowing the build. Fix this here.
