Subject: ARM: dts: apq8064: add ahci ports-implemented mask

From: Srinivas Kandagatla <[email protected]>

commit bb4add2ce991e4ec891b5a0287fd1ab77b631979 upstream.

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")
