drivers: timer: move initialization setup to drivers

Browse source 
The weak symbol sys_clock_driver_init has been removed, therefore moving
the init responsability to the drivers themselves. As a result, the init
function has now been made static on all drivers and moved to the
bottom, following the convention used in other areas.
