Do not set default values of KDUMP_CMDLINE and KDUMP_KIMAGE, and leave
them set by configure file since they are different for different
architectures. Take KDUMP_KIMAGE kdump kernel image for example:

    x86 is bzImage
    mips64 is vmlinux
    ppc is uImage
    arm is zImage

When run "kexec" in powerpc board, the kexec has a limit that
the kernel text and bss size must be less than 24M. But now
some kernel size exceed the limit. So we need to change the limit,
else will get the error log as below:

my_load:669: do
Could not find a free area of memory of 0x12400 bytes...
Could not find a free area of memory of 0x13000 bytes...
