Subject: [PATCH] Support MSI Poulsbo netbook U110/U115

The MSI U110/U115's DSDT have opregion declare, but i915 drm driver
does not support Poulsbo ship. It causes the acpi backlight control
interface not generate by i915 drm driver.
But, we are sure the MSI Poulsbo netbook U110/U115 have workable
_BCM,_BQC implementation in DSDT and it control brightness by using
EC but not opregion.

So, put a dmi detection in msi-laptop driver and also add wlan/bluetooth
rfkill support on U110/U115.
