powerpc: change CONFIG_PPC_STD_MMU_32 to CONFIG_PPC_BOOK3S_32 

Today we have:

config PPC_BOOK3S_32
        bool "512x/52xx/6xx/7xx/74xx/82xx/83xx/86xx"
        [depends on PPC32 within a choice]

config PPC_BOOK3S
        def_bool y
        depends on PPC_BOOK3S_32 || PPC_BOOK3S_64

config PPC_STD_MMU
	def_bool y
	depends on PPC_BOOK3S

config PPC_STD_MMU_32
	def_bool y
	depends on PPC_STD_MMU && PPC32

PPC_STD_MMU_32 is therefore redundant with PPC_BOOK3S_32.

In order to make the code clearer, lets use preferably PPC_BOOK3S_32.
This will allow to remove CONFIG_PPC_STD_MMU_32 in a later patch.
