- Introduce kernel_kseg0_end variable that marks first address in KSEG0

    available for use. All data below this address considered to be used
    by kernel. Along with kernel own data it might be symbol tables
    prepeared by trampoline code, boot loader service data passed for
    further analysis by kernel, etc... By default kernel_kseg0_end points
    to the end of loaded kernel.

- Introduce mips_postboot_fixup function. It checks for symbol information
    copied by ELF trampoline and passes it to KDB
