[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.

- depends on PPC_PS3 && EXPERIMENTAL
- bool "PS3 use lpar address space"
- default y
- help
- 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.
