[ Upstream commit e7e7e0d7beafebd11b0c065cd5fbc1e5759c5aab ]
If the clock tree is not fully populated when the timer-sun5i init code
is called, attempts to get the clock rate for the timer would fail and
return 0.
Make the init code for both clock events and clocksource check the
returned clock rate and fail gracefully if the result is 0, instead of
causing a divide by 0 exception later on.

[ Upstream commit 6e001f6a4cc73cd06fc7b8c633bc4906c33dd8ad ]
asm9260_timer_init misses a check for of_clk_get.
Add a check for it and print errors like other clocksource drivers.
