powerpc: add ISA v3.0 / v3.1 wait opcode macro
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).
