uv_time: add parameter to uv_read_rtc()
uv_read_rtc() is referenced by read member of struct clocksource clocksource_uv.
In include/linux/clocksource.h, read of struct clocksource is declared as:
cycle_t (*read)(struct clocksource *cs)
This got introduced recently in:
8e19608: clocksource: pass clocksource to read() callback
But arch/x86/kernel/uv_time.c was not properly converted by that pach.
This patch adds a dummy parameter (struct clocksource type) to uv_read_rtc() to
fix the incompatible reference in clocksource_uv, and add a NULL parameter in
all places where uv_read_rtc() gets called.
[ Impact: cleanup, address compiler warning ]
