Avoid writing same data to IoExpander and ClockBuffer
During initialization hsbp-manager sets zero at bit position of clock buffer register and IO output register that has a NVMe drive in it.
Code changes are made to make sure that if the bit positions are
already set to zero, we can avoid the write to clock buffer register
and IO output register.
Tested:
- Made sure the working of hsbp manager is not affected.
- Made sure that write to clock buffer register and IO output register
does not happen if we restart hsbp manager service, as bits are
already set to zeros.
