powerpc: Fix CamelCase checkpatch warnings

85xx, 86xx PowerPC folders have code variables with CamelCase naming conventions.
because of this code checkpatch script generates "WARNING: Avoid CamelCase".

Convert variables name to normal naming convention and modify board, driver
files with updated the new structure.
