[PATCH 1/2] powerpc: wii_defconfig: Disable Ethernet driver support code

[Jonathan Neuschäfer]

The Wii doesn't have built-in Ethernet and USB Ethernet adapters are in
a different menu. Disable CONFIG_ETHERNET to save some space in support
code for Ethernet drivers.

[PATCH 2/2] powerpc: wii_defconfig: Enable GPIO-related options

[Jonathan Neuschäfer]

Now that there's a GPIO driver for the Wii, let's enable the following
drivers:

- the GPIO driver itself
- gpio-keys
- gpio-poweroff
- gpio-leds and a few LED triggers

Oops, this doesn't work without first enabling CONFIG_NEW_LEDS and
CONFIG_LEDS_TRIGGERS. I'll send a v2.
