sh: Fix up asm-generic/ptrace.h fallout.
There was an ordering issue with regards to instruction_pointer() being used in profile_pc() prior to the asm-generic/ptrace.h include, which subsequently provided the instruction_pointer() definition. In the interest of simplicity we simply open-code the regs->pc deref for the profile_pc() definition instead. The FP functions were also broken due to a lack of a common regs->fp, so provide a common GET_FP() that is safe for both architectures in order to fix up the frame pointer helpers too.
