ARM: keystone2: rename init_meminfo to pv_fixup

Browse source 
The init_meminfo() method is not about initialising meminfo - it's about
fixing up the physical to virtual translation so that we use a different
physical address space, possibly above the 4GB physical address space.
Therefore, the name "init_meminfo()" is confusing.

Rename it to pv_fixup() instead.
