Function parse_crashkernel() could be misunderstood as a generic interface parsing all possible crashkernel kernel parameters. Hence, rename parse_crashkernel() to parse_crashkernel_common() to differentiate it from parse_crashkernel_high() and parse_crashkernel_low(), to remove possible ambiguity.
