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
- COMMON_CLK_DEBUG: no longer exists

Add some features to tegra_defconfig:
* Tegra+MAX98090 audio machine driver, as used on the Venice2 board.
* AMX3722 PMIC, as used on the Venice2 board.
* ChromeOS embedded controller, for the Venice2 keyboard.

Also, rebuild tegra_defconfig on a more recent kernel (3.13-rc1) to
minimize irrelevant diffs showing up when people edit the file.

Enable some new features:
* The Tegra114 SPI controller, for Dalmore's SPI flash.
* Set all the GPIO leds triggers to their "if you don't know, say X"
  value, so there are some useful triggers for the gpio-leds support.
* TPS65090 charger, for Dalmore.
* ASoC RT5640 machine driver, for audio on Beaver and Dalmore.

Also, rebuild tegra_defconfig on top of linux-next. This should make it
easier to create future defconfig patches, without extraneous diffs.
This should introduce no changes; simply moving entries around due to
Kconfig ordering changes. The apparent exceptions are:

* AUTO_ZRELADDR: Selected by ARM multi-platform support.
* MTD_CHAR: Removed in Kconfig.

Removed:

* MACH_HARMONY
* MACH_PAZ00
* MACH_TRIMSLICE

  These used to enable board support for individual boards. Now that we
  only support device tree, these options have been removed.

Added:

* TEGRA_PCI

  This used to be selected by the board options above. Select this
  explicitly now that the board options have been removed.

* TEGRA_DEBUG_UART_AUTO_ODMDATA

  This makes the kernel automatically pick a UART for earlyprintk. It's
  likely to be a useful option for everyone.

* PWM
* PWM_TEGRA

  Enable the new PWM subsystem, and the Tegra driver within it.

* GPIO_PCA953X
* GPIO_PCA953X_IRQ
* MFD_MAX8907
* REGULATOR_MAX8907
* RTC_DRV_MAX8907
* RTC_DRV_TPS65910

  Various drivers required for the Whistler board.

* RTC_INTF_SYSFS
* RTC_INTF_PROC
* RTC_INTF_DEV

  Some RTC options that Kconfig help implies should typically be
  enabled.

* Wifi chip (rt3070)
* Bluetooth (btusb)
* Camera (uvcvideo)
* 3G modem (acm and wdm)
* rfkill
* GPIO LEDs
* NVEC

  Various devices and features found on PAZ00 boards.

  Some of these are enabled as modules because they are not needed for
  boot and will not be used on other boards. Wifi also needs to be
  module because of the firmware loader.

  The update also enabled support for the rfkill switch, the Wifi LED and
  the nvec power and led driver which got lost in the past.

* DEVTMPFS, TMPFS_POSIX_ACL

  These are mandatory on modern linux distros.
