Subject: libahci: save port map for forced port map
From: Srinivas Kandagatla <srinivas.kandagatla@linaro.org>
commit 2fd0f46cb1b82587c7ae4a616d69057fb9bd0af7 upstream.
In usecases where force_port_map is used saved_port_map is never set,
resulting in not programming the PORTS_IMPL register as part of initial
config. This patch fixes this by setting it to port_map even in case
where force_port_map is used, making it more inline with other parts of
the code.
Fixes: 566d1827df2e ("libata: disable forced PORTS_IMPL for >= AHCI 1.3")
