Enhancement to increase the threshold of corrected single-bit errors

The threshold of corrected single-bit errors is increased from 32 to 1024, and the alarm severity is changed from Major to Minor for those error messages. There is no operational impact upon corrected single-bit errors. Also, a log message is added to display how many single-bit errors have been corrected between the reported events as follows: EA[0:0]: HMCIF Rx: Link0: Corrected single bit errordetected in HMC 0 - Total count 25 EA[0:0]: HMCIF Rx: Link0: Corrected single bit errordetected in HMC 0 - Total count 26
