[PATCH v2 2/2] PCI/ACPI: Remove OSC_PCI_SUPPORT_MASKS and OSC_PCI_CONTROL_MASKS

[Joerg Roedel]

From: Joerg Roedel <jroedel@xxxxxxx>

These masks are only used internally in the PCI Host Bridge _OSC
negotiation code, which already makes sure nothing outside of these
masks is set. Remove the masks and simplify the code.
