These clock aliases can also be used when configuring the system timers and allow us to remove the current definitions, simplifying the code. Please note that for OMAP4/5 devices (unlike OMAP2/3 devices), there is no clock alias for "timer_sys_ck" with NULL as the device name. Therefore we still need to use the alias "sys_clkin_ck" for these devices.
