sata_mv: Fix broken Marvell 7042 support. The Marvell 7042 chip is more or less the same as the 6042 internally, but sports a PCIe bus. Despite having identical SATA cores, the 7042 does differ from its PCI bus counterparts in placment and layout of certain bus related registers. This patch fixes sata_mv to distinguish between the PCI bus registers of earlier chips, and the PCIe bus registers of the 7042. Specifically, move the offsets and bit patterns for the PCI/PCIe interrupt cause/mask registers into the struct mv_host_priv, as these values differ between the 6xxx and 7xxx series chips. This fixes the driver to not access reserved PCI addresses, and prevents the lockups reported in linux-2.6.24 with 7042 boards. Also add a new PCI ID for the Highpoint 2300 7042-based board that I'm using for testing this stuff here. Tested with Marvell 6081 + 7042 chips, on x86 & x86_64.
