OCMB MMIO error handling

Added the following
-Error checking and FRU isolation on explorer side
-Cleaned up MMIO write error handling to read an MMIO
 error register
-Fixed and enabled MMIO test cases
-Moved parameter checking and channel checkstop checking
 into seperate functions.
-Only check for channel checkstop for the channel that an
 OCMB is connected to.
-Switch to using I2C on first MMIO failure.
