We may need to access various hardware bits in the .global_resources() hook, so move the call to occur after enabling all the newly required power wells, but before disabling all the now unneeded wells. This should guarantee that we have all the sufficient hardware resources available during the .global_resources() call. And if not, any additional resources must be explicitly acquired by the .global_resorces() hook. For instance on VLV/CHV we need to access the gunit mailbox so that we can talk to punit/cck over sideband. In addition some PFI credit reprogramming may need to be addes as well, which may require the disp2d well. This should also make the power domain refcounts consistent on platforms which don't have a .global_resource() hook since now they too will call modeset_update_crtc_power_domains() which will drop the init power. Previously init power was just left enabled for such platforms.
