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
