[PATCH 0/3] 82xx: Add the support for Wind River SBC PowerQUICCII

These 3 patches add the powerpc support of Wind River SBC PowerQUICCII.

1) Currently, some mpc82xx platform hooks in mpc82xx_ads.c are actually not specific to ads board. So the 1st patch 
makes them be shared by different 82xx boards.

2) The 2nd patch make 'cpm_uart_of_init' be able to parse SMC uart in DTS

3) The 3rd patch is the platform codes, defconfig and dts for Wind River SBC PowerQUICCII 82xx board.

Any comment is welcome.

Thanks
