powerpc/8xx: Define a MODULE area below kernel text
On the 8xx, TASK_SIZE is 0x80000000. The space between TASK_SIZE
and PAGE_OFFSET is not used.
In order to benefit from the powerpc specific module_alloc()
function which allocate modules with 32 Mbytes from
end of kernel text, define MODULES_VADDR and MODULES_END.
Set a 256Mb area just below PAGE_OFFSET, like book3s/32.
