ARM: at91: sama5d27-som1: clean up lowlevel.c
In ARM, stack decrements before storing values, so decrementing a number from the stack base is unnecessary. Existing instances of this were removed in 6b3dc4abd8 ("ARM: Cleanup stack offset cargo cult"), but the sama5d27-som1 board was added later than that. Fix the cargo cult here as well and while at it, turn a macro that doesn't need to be one into a static inline function.
