[PATCH 5.10.y 04/15] clocksource/drivers/sp804: Do not use timer namespace for timer_shutdown() function

[ Upstream commit 6e1fc2591f116dfb20b65cf27356475461d61bd8 ]

A new "shutdown" timer state is being added to the generic timer code. One
of the functions to change the timer into the state is called
"timer_shutdown()". This means that there can not be other functions
called "timer_shutdown()" as the timer code owns the "timer_*" name space.

Rename timer_shutdown() to evt_timer_shutdown() to avoid this conflict.
