Now there are parse_crashkernel_high() and parse_crashkernel_low()
parsing crashkernel=,high|low. 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.
