mb/gigabyte/ga-g41m-es2l: Fix ACPI IRQ settings for SATA 

Previously, due to a bug in devicetree and incorrect IRQ
settings in ACPI, SATA controller would not initialize
any HDDs in the OS, even though it worked in SeaBIOS.
The devicetree setting is not needed because SATA must
function in "plain" mode on this board, as "combined" mode
does not work at all.
