Jacky Bai 3d5c2f8e75 clocksource/drivers/imx-tpm: Fix next event not taking effect sometime 
The value written into the TPM CnV can only be updated into the hardware
when the counter increases. Additional writes to the CnV write buffer are
ignored until the register has been updated. Therefore, we need to check
if the CnV has been updated before continuing. This may require waiting for
1 counter cycle in the worst case.
