xtensa: use pre- and postincrement FP load/store when available
Earlier versions of xtensa FPU used to support preincrement FP load and
store instructions (lsiu/ssiu). Recent FPU supports postincrement FP
load and store instructions only (lsip/ssip). Use configuration macro to
decide which version is available.
