Move AVR32 kernel patches to target/device/Atmel/arch-avr32
Add linux-2.6.22.1-008-atmel-gpio_mouse-setup-for-atstk1000-board.patch
Move AT91 kernel patches to target/device/Atmel/arch-arm
Change name from "target/device/Atmel/Linux" to "target/device/Atmel/linux"
"kernel-headers" will apply all patches in $(LINUX26_KERNEL_PATCH_DIR)
if this is available.
Define LINUX26_KERNEL_PATCH_DIR in target/device/Atmel/Makefile.in
as above "arch-arm/kernel-patches-..." if an AT91 or
as above "arch-avr32/kernel-patches-..." if an AVR32 target is selected
Test build done for arm,avr32 and x86
