[ 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.
Fixes: 566d1827df2e ("libata: disable forced PORTS_IMPL for >= AHCI 1.3")
