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.
