[XEN][POWERPC] Fix PHDR issues with large .data.percpu sections

This patch tells the link to only create one PHDR and place all sections
in it, also removing an unrequired mapping for the .data.percpu section.

This avoids the "Not enough room for program headers (allocated 2, need 3)"

Booted on a JS20.
