ARM: 7166/1: Use PMD_SHIFT instead of PGDIR_SHIFT in dma-consistent.c

Browse source 
Commit 99d1717d (ARM: Add init_consistent_dma_size()) introduces dynamic
allocation of the consistent_pte array. The number of PTEs should be
calculated based on the number of PMD entries rather than PGD, hence the
PMD_SHIFT.
