We don't need to do this on x86_32 because cleanup_highmap is not called on x86_32. Besides lowering max_pfn_mapped on x86_32 has the unwanted side effect of limiting the amount of memory available for the 1:1 kernel pagetable allocation. This patch reverts the x86_32 part of the original patch.

With this patch applied port CN22 is driven by the recently added renesas_usbhs driver using the first USB controller included in sh7372 aka USBHS0. Hotplugging of USBHS0 unfortunately has to be handled by software polling. The sh7372 SoC itself obviously supports hotplug notification by IRQ but on the Mackerel board this IRQ happens to be used for the touch screen. Also fix the pinmux configuration to avoid setting up unused pins and fix minor spelling errors.

The earlier attempts (24bdb0b62cc82120924762ae6bc85afc8c3f2b26) at fixing this problem caused other problems to surface (PV guests with no PCI passthrough would have SWIOTLB turned on - which meant 64MB of precious contingous DMA32 memory being eaten up per guest). The problem was: "on xen we add an extra memory region at the end of the e820, and on this particular machine this extra memory region would start below 4g and cross over the 4g boundary: [0xfee01000-0x192655000) Unfortunately e820_end_of_low_ram_pfn does not expect an e820 layout like that so it returns 4g, therefore initial_memory_mapping will map [0 - 0x100000000), that is a memory range that includes some reserved memory regions." The memory range was the IOAPIC regions, and with the 1-1 mapping turned on, it would map them as RAM, not as MMIO regions. This caused the hypervisor to complain. Fortunately this is experienced only under the initial domain so we guard for it.
