clk: vf610: improve handling case that cpu frequency can't be changed
Currently we get a nasty error message if the cpu clock can't be
changed:
DDRC is clocked by PLL1, can't switch CPU clockinitcall vf610_switch_cpu_clock+0x1/0x198 failed: Invalid argument
So let's do the following:
- factor out the check from vf610_switch_cpu_clock_to_500mhz() and
vf610_switch_cpu_clock_to_400mhz
- if clock can't be changed, don't treat it as an error
- don't call clock notifier chain if clock can't be changed
- add trailing newline to the warning message
