mb/dell/optiplex_9020: Fix SATA port maps
Previously incorrect sets of SATA ports were enabled. There are no publically available schematics, but I am almost certain the new values are correct. The original 0x33 value was carlessly copy pasted, and only enables ports 0, 1, 4, 5, leaving 2, 3 disabled. On the SFF, with 0x33 only the first 2 ports worked. I have verified by plugging in devices under the stock firmware that 0, 1, 2 are the ones that should be enabled, so setting the value to 0x7 per datasheet. This was also tested in practice to work. I don't have an MT, but I was told the two white ports didn't work with 0x33, so those are most certainly ports 3, 4, hence me setting the value to 0xf. If the MT's working ports are port 0, 1 on the PCH this is correct.
