Move shared code from mpc5121_ads.c to new file mpc512x_shared.c
mpc512x_find_ips_freq -> unchanged
contents of mpc5121_ads_init_IRQ -> mpc512x_init_IRQ
looking for fsl,mpc5121-ipic instead of fsl,ipic
mpc5121_ads_declare_of_platform_devices ->
mpc5121_declare_of_platform_devices
and use compatible for lookup instead of node name
Add new generic board setup mpc5121_generic.c
