Add devm_arch_phys_wc_add() and devm_arch_io_reserve_memtype_wc() for automatic cleanup of writecombine setup.
Several DRM drivers use the non-managed functions for setting their framebuffer memory to write-combine access. Convert ast, mgag200 and vboxvideo. Remove rsp clean-up code form drivers.
Tested on mgag200 hardware.
