clk: ti: dra7: fix kernel boot with arg 'clocksource=gp_timer'
The OMAP Platform code provides possibility to select GP Timer as default clocksource instead of counter_32K by using bootcmd parameter 'clocksource', but the system will crash during early boot when this option is used on dra7 or omap5 platforms, because it will hit BUG() statement: omap2_gptimer_clocksource_init ->BUG_ON(res); This happens because clk_dev alias "sys_clkin_ck" is not registered. Hence, fix it by adding missing "sys_clkin_ck" clk_dev aliases definitions for omap5 and dra7.
