arm: lib: Fix uldivmod.S build on Thumb2

Browse Source 
This assembler source won't build in Thumb2 mode, so fix it adding
the necessary Thumb2 conditional macros from unified.h .

This patch also defines CONFIG_THUMB2_KERNEL and CONFIG_ARM_ASM_UNIFIED
which is necessary for correct build of these files both in ARM and
Thumb mode, just like Linux does.
