core/init: remove master_cpu parameter
master_cpu is used to determine the ChipTOD master if no ChipTOD
information is available in the HDAT. However, it is set to zero at every
skiboot entry point (fdt_entry, the 0x180 FSP entry and
opal_boot_trampoline) and is otherwise unused. This patch removes this
passing around and uses the boot CPU PIR to find the ChipTOD master rather
than zero.
