powerpc/82xx: rename and update mgcoge board support
The mgcoge board from keymile is now base for some other similar boards. Therefore the board specific name mgcoge was renamed to a generic name km82xx. Additionally some enhancements were made: - rework partition table in dts file - add cpm2_pio_c gpio controller in dts file - update defconfig - add pin description for SCC1 - add pin description and configuration for USB Signed-off-by: Holger Brunck <holger.brunck@keymile.com> Acked-by: Heiko Schocher <hs@denx.de> CC: Benjamin Herrenschmidt <benh@kernel.crashing.org> CC: Heiko Schocher <hs@denx.de> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
