4.4-stable review patch. If anyone has any objections, please let me know.
------------------
[ Upstream commit bb4add2ce991e4ec891b5a0287fd1ab77b631979 ]
This patch adds new ports-implemented mask, which is required to get achi working on the mainline. Without this patch value read from PORTS_IMPL register which is zero would not enable any ports for software to use.
