This function is not used outside of this translation unit so mark it as
static to resolve the warning.

When building allmodconfig, there is a warning about TIMER_ENABLE being
redefined:
drivers/clocksource/timer-oxnas-rps.c:39:9: error: 'TIMER_ENABLE' macro redefined [-Werror,-Wmacro-redefined]
#define TIMER_ENABLE BIT(7)
^
arch/hexagon/include/asm/timer-regs.h:13:9: note: previous definition is here
#define TIMER_ENABLE 0

1 error generated.
The values in this header are only used in one file each, if they are
used at all. Remove the header and sink all of the constants into their
respective files.
TCX0_CLK_RATE is only used in arch/hexagon/include/asm/timex.h
TIMER_ENABLE, RTOS_TIMER_INT, RTOS_TIMER_REGS_ADDR are only used in
arch/hexagon/kernel/time.c.
SLEEP_CLK_RATE and TIMER_CLR_ON_MATCH have both been unused since the
file's introduction in commit 71e4a47f32 ("Hexagon: Add time and timer
functions").
TIMER_ENABLE is redefined as BIT(0) so the shift is moved into the
definition, rather than its use.

request_irq() is preferred over setup_irq(). Invocations of setup_irq()
occur after memory allocators are ready.
setup_irq() was required in older kernels as the memory allocator was not
available during early boot.
Hence replace setup_irq() by request_irq().

In preparation for making the clockevents core NTP correction aware,
all clockevent device drivers must set ->min_delta_ticks and
->max_delta_ticks rather than ->min_delta_ns and ->max_delta_ns: a
clockevent device's rate is going to change dynamically and thus, the
ratio of ns to ticks ceases to stay invariant.
Make the hexagon arch's clockevent driver initialize these fields
properly.
This patch alone doesn't introduce any change in functionality as the
clockevents core still looks exclusively at the (untouched) ->min_delta_ns
and ->max_delta_ns. As soon as this has changed, a followup patch will
purge the initialization of ->min_delta_ns and ->max_delta_ns from this
driver.

Migrate hexagon driver to the new 'set-state' interface provided by
clockevents core, the earlier 'set-mode' interface is marked obsolete
now.
This also enables us to implement callbacks for new states of clockevent
devices, for example: ONESHOT_STOPPED.
We weren't doing anything in the ->set_mode() callback. So, this patch
doesn't provide any set-state callbacks.
