s390/time: Fix clk type in get_tod_clock
commit 0f8a206df7c920150d2aa45574fba0ab7ff6be4f upstream.
Clang warns:

../arch/s390/include/asm/timex.h:160:20: warning: passing 'unsigned char
[16]' to parameter of type 'char *' converts between pointers to integer
types with different sign [-Wpointer-sign]
get_tod_clock_ext(clk);
^~~
../arch/s390/include/asm/timex.h:149:44: note: passing argument to
parameter 'clk' here
static inline void get_tod_clock_ext(char *clk)
^
Change clk's type to just be char so that it matches what happens in
get_tod_clock_ext.
