[NV110] HP Pavilion 15 with Maxwell 950M fails to read BIOS (fix included)

Description
(Please tell me what information to attach and I will attach it)
HP Pavilion 15 (Skylake) with Maxwell 950M fails to load the whole BIOS. The ACPI "fast" method is selected first, which partially loads the BIOS with a score of 6, which prevents the ACPI "slow" method which actually works from ever being attempted.
To work around this I changed the name of the ACPI methods to "ACPIF" and "ACPIS" respectively, so that I could issue this parameter to target the slow method directly:
nouveau.config=NvBios=ACPIS
