    powerpc: consider CPU count while calculating crashkernel value

    The next patch in the series adds more CPUs to the capture kernel,
    which increases the memory requirement for the capture kernel.
    Experiments show that powerpc needs 1 MB of additional memory for every
    CPU added.

    Therefore, while calculating the crashkernel size, make sure to include
    an additional 1 MB for every CPU configured in the capture kernel.

    The changes are implemented in such a way that if the user changes the
    nr_cpus value in the kdump configuration, the script will adapt
    accordingly.

Since the find_nr_cpus() function can not get the bash variable
$FADUMP_COMMANDLINE_APPEND and $KDUMP_COMMANDLINE_APPEND in RHEL-9,
extract them from /etc/sysconfig/kdump directly
