[PATCH v2] ata: ahci: Use correct DMI identifier for ASUSPRO-D840SA LPM quirk

ASUS store the board name in DMI_PRODUCT_NAME rather than
DMI_PRODUCT_VERSION. (Apparently it is only Lenovo that stores the
model-name in DMI_PRODUCT_VERSION.)

Use the correct DMI identifier, DMI_PRODUCT_NAME, to match the
ASUSPRO-D840SA board, such that the quirk actually gets applied.
