[Alison Wang] If GENERIC_TIMER_CLK is used and CONFIG_TIMER_CLK_FREQ is removed,
I need to modify the generic codes which use CONFIG_TIMER_CLK_FREQ in
arch/arm/cpu/armv7/nonsec_virt.S. Some other platforms may be affected. So I
remove GENERIC_TIMER_CLK in v1.

What's your idea?

Best Regards,
Alison Wang
