CRIS: Change DEFINE_PER_CPU of current_pgd to be non volatile. 

The DEFINE_PER_CPU of current_pgd was on CRIS defined using volatile,
which is not needed. Remove volatile.

Tested on an ARTPEC-3 (CRISv32) board.

tj: extern DEFINE_PER_CPU() replaced with DECLARE_PER_CPU()

[ Impact: code cleanup ]
