The mips_cps_boot_vpes function previously included code to retrieve pointers to the core & VPE boot configuration structs. These structures were used both by mips_cps_boot_vpes and by its mips_cps_core_entry callsite. In preparation for skipping the call to mips_cps_boot_vpes on some invocations of mips_cps_core_entry, pull the calculation of those pointers out into a separate function such that it can continue to be shared.
