ixp4xx: Add back support for Netgear WG302 v1

Browse Source 
The WG302 v1 has 32MB of RAM so it can easily run OpenWrt,
however it lacks much flash: only 8 MB.

By just using the flash for rootfs and booting a kernel over
TFTP it works just fine.

Subject: [PATCH] ARM: dts: ixp4xx: Fix up PCI on WG302
Looking at the board file for WG302 v2 was not a good idea
because the GPIO IRQ for slot 2 differs, and v1 uses GPIO
10 instead of GPIO 9. Fix it up.
