linux-user/sparc: Use WREG constants in sparc/target_cpu.h
This fixes a naming bug wherein we used "UREG_FP" to access the stack pointer. OTOH, the "UREG_FP" constant was also defined incorrectly such that it *did* reference the stack pointer. Note that the kernel legitimately uses the name "FP", because it utilizes the rolled stack window in processing the system call.
