This change includes everything required to enable audio on Harmony, except
those parts which rely on code not currently in Tegra's for-next branch, i.e.
except those parts which rely on merges of the Tegra I2C driver or latest
ASoC subsystem.

* Define GPIO names for audio-related GPIOs
* Set up platform data and platform device for ASoC machine driver
* Register audio-related platform devices
* Initialize audio-related clocks
* Correctly configure pinmux and GPIO enables for audio-related pins

This ensures they're kept in sync between platform_data definitions and
the GPIO table initialization.

Add the 3 sdhci devices that are available on Harmony as
platform devices. Two go to slots (one 4-lane, one 8-lane),
and one goes to onboard wifi.

Move tegra_common_init to tegra_init_early, and set it
as the init_early entry in the machine struct.
Initializes the clocks earlier so that timers can enable
their clocks.

Also reorders the members in the Harmony and Trimslice
boards' machine structs to match the order they are
called in.

Since we're now using addruart to establish the debug mapping, we can
remove the io_pg_offst and phys_io members of struct machine_desc.

The various declarations were removed using the following script:

  grep -rl MACHINE_START arch/arm | xargs \
  sed -i '/MACHINE_START/,/MACHINE_END/ { /\.\(phys_io\|io_pg_offst\)/d }'

[ Initial patch was from Jeremy Kerr, example script from Russell King ]

The patch "ARM: Remove DISCONTIGMEM support" removed the node id from
the meminfo struct and the PHYS_TO_NID macro, causing compilation errors:

arch/arm/mach-tegra/board-harmony.c: In function 'tegra_harmony_fixup':
arch/arm/mach-tegra/board-harmony.c:94: error: 'struct membank' has no member named 'node'
arch/arm/mach-tegra/board-harmony.c:94: error: implicit declaration of function 'PHYS_TO_NID'

v2: fixes from Russell King
	- include linux/io.h instead of mach/io.h

v3: fixes from Linus Walleij
	- remove /16 * 16 from UART clock

v3:
	- Fix checkpatch issues
	- make board init calls explicit
	- use clock init table to set clocks
