fdt: Fix regression in fdt_pack_reg()
After commit 933cdbb479: "fdt: Try to use fdt_address_cells()/fdt_size_cells()"
I noticed that allwinner boards would no longer boot.
Switching to fdt_address_cells / fdt_size_cells changes the result from
bytes to 32 bit words, so when we increment pointers into the blob, we must
do so by 32 bit words now.
This commit makes allwinner boards boot again.

ARM: UniPhier: add dummy gpio.h to enable CONFIG_OF_CONTROL
If CONFIG_OF_CONTROL is enabled, lib/fdtdec.c is compiled.
It includes <asm/gpio.h> and then <asm/gpio.h> includes
<asm/arch/gpio.h>. Consequently, all the SoCs that enable
CONFIG_OF_CONTROL must have <asm/arch/gpio.h> even if they do not
support GPIO.
In the first place, GPIO has nothing to do with OF_CONTROL.
It is wrong that lib/fdtdec.c includes GPIO functions; it should
be split into two files, FDT-common things and GPIO things.
It is, however, a pretty big work to fix that correctly.
This is a compromised commit to add a dummy <asm/arch/gpio.h>

will be removed after FDT-GPIO stuff is fixed correctly.

pci: Add general support for execution of video ROMs
Some platforms don't have native code for dealing with their video

from the old PC days where a ROM was provided and executed during startup.
Even now, these ROMs are supplied as a way to set up video. It avoids the
code for every video chip needing to be provided in the boot loader. But
it makes the video much less flexible - e.g. it is not possible to do
anything else while the video init is happening (including waiting hundreds
of milliseconds for display panels to start up).
In any case, to deal with this sad state of affairs, provide an API for
