ahci: asm1166: correct count of reported ports
[ Upstream commit 0077a504e1a4468669fd2e011108db49133db56e ]
The ASM1166 SATA host controller always reports wrongly,
that it has 32 ports. But in reality, it only has six ports.
This seems to be a hardware issue, as all tested ASM1166
SATA host controllers reports such high count of ports.
Example output: ahci 0000:09:00.0: AHCI 0001.0301
32 slots 32 ports 6 Gbps 0xffffff3f impl SATA mode.
By adjusting the port_map, the count is limited to six ports.
New output: ahci 0000:09:00.0: AHCI 0001.0301
32 slots 32 ports 6 Gbps 0x3f impl SATA mode.
