The wait instruction encoding changed between ISA v2.07 and ISA v3.0.
In v3.1 the instruction gained a new field.
Update the PPC_WAIT macro to the current encoding. Rename the older
incompatible one with a _v203 suffix as it was introduced in v2.03
(the WC field was introduced in v2.07 but the kernel only uses WC=0).

e500 idle setup is a bit messy.
e500_idle() is used for PPC32 while book3e_idle() is used for PPC64.
As they are mutually exclusive, call them all e500_idle().
Use CONFIG_MPC_85xx instead of PPC32 + E500 in Makefile and rename
idle_e500.c to idle_85xx.c .
Rename idle_book3e.c to idle_64e.c and remove #ifdef PPC64 in
as it's only built on PPC64.
