[PATCH] powerpc: Fix "integer constant is too large" build failure

My powerpc-linux-gnu-gcc v4.4.5 compiler can't build a 32-bit kernel
any more:

arch/powerpc/lib/sstep.c: In function 'do_popcnt':
arch/powerpc/lib/sstep.c:1068: error: integer constant is too large for 'long' type
arch/powerpc/lib/sstep.c:1069: error: integer constant is too large for 'long' type
arch/powerpc/lib/sstep.c:1069: error: integer constant is too large for 'long' type
arch/powerpc/lib/sstep.c:1070: error: integer constant is too large for 'long' type
arch/powerpc/lib/sstep.c:1079: error: integer constant is too large for 'long' type
arch/powerpc/lib/sstep.c: In function 'do_prty':
arch/powerpc/lib/sstep.c:1117: error: integer constant is too large for 'long' type

This file gets compiled with -std=gnu89 which means a constant can be
given the type 'long' even if it won't fit. Fix the errors with a 'ULL'
suffix on the relevant constants.

Fixes: 2c979c489fee ("powerpc/lib/sstep: Add prty instruction emulation")
Fixes: dcbd19b48d31 ("powerpc/lib/sstep: Add popcnt instruction emulation")

This change was compile tested but not regression tested.
