x86: Move init_gbpages() to setup_arch()
The init_gbpages() function is conditionally called from
init_memory_mapping() function. There are two call-sites where
this 'after_bootmem' condition can be true: setup_arch() and
mem_init() via pci_iommu_alloc().
Therefore, it's safe to move the call to init_gbpages() to
setup_arch() as it's always called before mem_init().
This removes an after_bootmem use - paving the way to remove
all uses of that state variable.
