pm: Fix wrong type promotion

Browse Source 
In pm_system_suspend there is a possible invalid type promotion
in sys_clock_set_timeout(MAX(0, ticks - exit_latency_ticks), true);

ticks is int32_t and exit_latency_ticks is uint32_t consequently
ticks is promoted to uint32_t resulting in a possible underflow and
setting a wrong value in sys_clock_set_timeout().

Fixes #100005
