powerpc/sgy_cts1000: Fix gpio_halt_cb()'s signature
Halt callback in struct machdep_calls is declared with __noreturn
attribute, so omitting that attribute in gpio_halt_cb()'s signatrue
results in compilation error.
Change the signature to address the problem as well as change the code
of the function to avoid ever returning from the function.
