x86: do not PSE on CONFIG_DEBUG_PAGEALLOC=y
get more testing of the c_p_a() code done by not turning off
PSE on DEBUG_PAGEALLOC.
this simplifies the early pagetable setup code, and tests
the largepage-splitup code quite heavily.
In the end, all the largepages will be split up pretty quickly,
so there's no difference to how DEBUG_PAGEALLOC worked before.
