[RESEND,v2,06/14] hexagon: switch to generic version of pte allocation

Hi,

The patch below was a part of of the series that switched a couple of
arches to use generic versions of pte_{alloc,free}_one.

Unfortunately, it fell between the cracks and I've noticed this only today :(

I understand that merge window is going to close in couple of hours, but
maybe this may still go in?
