sky2: Disable MSI on yet another ASUS boards (P6Xxxx)

[ Upstream commit 189308d5 ]

A similar workaround for the suspend/resume problem is needed for yet
another ASUS machines, P6X models.  Like the previous fix, the BIOS
doesn't provide the standard DMI_SYS_* entry, so again DMI_BOARD_*
entries are used instead.
