All Allwinner A20 boards we support can only use either EMAC or GMAC,
as they share the same pins. As we have switched all supported to
GMAC, we should alias GMAC (the active controller) as ethernet0,
so u-boot will insert the MAC address for the correct controller.

TI_EDMA fell out of automatically selected options in the multi_v7

we need to re-enable explicitly to not regress some platforms.

DEBUG_FS used to be selected by COMMON_CLK_DEBUG, which was enabled
by tegra_defconfig. However, this config option no longer exists, so
no longer selects DEBUG_FS, and nothing else selects it either. So,
"make tegra_defconfig" no longer enables DEBUG_FS in .config.

Rebuild tegra_defconfig on top of next-20140424, while manually
re-enabling DEBUG_FS.

Reasons for removed entries are:
- I2C_MUX: selected by MEDIA_SUBDRV_AUTOSELECT
- DRM_PANEL: selected by DRM_TEGRA
- NEW_LEDS: selected by many things; at least VT
- LEDS_CLASS: selected by many things; at least VT
- LEDS_TRIGGERS: selected by many things; at least VT

multi_v7_defconfig was missing a large number of options that were in
tegra_defconfig. This patch adds them. The changes fall into the
following categories:

* Enable more Tegra SoC options/drivers.
* Enable more drivers for Tegra boards.
* Enable more options that are useful for running distros.

The patch removes a few lines as well, simply because those options are
now selected by something else, and "make savedefconfig" removes them. I
verified that the options appear in .config after
"make multi_v7_defconfig".

The use of phys_to_machine and machine_to_phys in the phys<=>bus conversions
causes us to lose the top bits of the DMA address if the size of a DMA address is not the same as the size of the phyiscal address.

This can happen in practice on ARM where foreign pages can be above 4GB even
though the local kernel does not have LPAE page tables enabled (which is
totally reasonable if the guest does not itself have >4GB of RAM). In this
case the kernel still maps the foreign pages at a phys addr below 4G (as it
must) but the resulting DMA address (returned by the grant map operation) is
much higher.

This is analogous to a hardware device which has its view of RAM mapped up
high for some reason.

This patch makes I/O to foreign pages (specifically blkif) work on 32-bit ARM
systems with more than 4GB of RAM.
