Subject: sh: Defer to asm-generic/device.h.

Now that the hwblk use cases have been ripped out, we can revert to
asm-generic/device.h for the device/platform device arch data structures.

Subject: sh: fix the sh_mmcif_plat_data in board-sh7757lcr

The board has an eMMC chip, so we cannot remove the chip.
In this case, we have to set the MMC_CAP_NONREMOVABLE to the caps
parameter.

Subject: sh: use the the PCI channels's io_map_base

commit 43db595e8b5d78ce5ad2feab719814a76e3ad2e5
(sh: switch to GENERIC_PCI_IOMAP)
failed to take into account the PCI channels's
io_map_base for mapping IO BARs.
This also caused a new warning on sh.

Fix this, without re-introducing code duplication,
by setting NO_GENERIC_PCI_IOPORT_MAP
and supplying a sh-specific __pci_ioport_map.
