powerpc/mm: Fix return type of pgd_val()
Commit 6b0e82791bd0 ("powerpc/e500: switch to 64 bits PGD on 85xx
(32 bits)") switched PGD entries to 64 bits, but pgd_val() returns
an unsigned long which is 32 bits on PPC32. This is not a problem
for regular PMD entries because the upper part is always NULL, but
when PMD entries are leaf they contain 64 bits values, so pgd_val()
must return an unsigned long long instead of an unsigned long.
Also change the condition to CONFIG_PPC_85xx instead of CONFIG_PPC_E500
as the change was meant for 32 bits only. Allthough this should be
harmless on PPC64, it generates a warning with pgd_ERROR print.
Fixes: 6b0e82791bd0 ("powerpc/e500: switch to 64 bits PGD on 85xx (32 bits)")
