Christophe Leroy e7a9af8c93 powerpc/mm: Fix size of allocated PGDIR ...

Commit 6b0e82791b ("powerpc/e500: switch to 64 bits PGD on 85xx
(32 bits)") increased the size of PGD entries but failed to increase
the PGD directory.

Use the size of pgd_t instead of the size of pointers to calculate
the allocated size.
