linux-user/sparc: Use WREG constants in sparc/target_cpu.h

Browse Source 
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.
