[POWERPC] PS3: Remove lpar address workaround
Remove the PS3 workaround needed to support sparsemem SPU mappings.
The SPU mappings no longer use sparsemem, so this workaround is no
longer needed.

This support is mainly for Linux kernel development. If unsure,
say N.

- This option is solely for experimentation by experts. Disables
- translation of lpar addresses. SPE support currently won't work
- without this set to y.

- If you have any doubt, choose the default y.
