timer: Pass function down to initialization routines
In preparation for removing more macros, pass the function down to the initialization routines instead of doing it in macros. Cc: Thomas Gleixner <tglx@linutronix.de> Cc: John Stultz <john.stultz@linaro.org> Cc: Stephen Boyd <sboyd@codeaurora.org> Signed-off-by: Kees Cook <keescook@chromium.org>
