parisc: Use generic init_task

Browse Source 
Same code, except: The alignment of init_thread_union is handled via
the linker script, so no point to have it with the data structure. The
extra asm(".data") looks like a leftover from an asm to C conversion
and is pointless.

Use the generic version.

Move the page table data to parisc/mm/init.c and get rid of
parisc/../init_task.c
