Hari Bathini 2e6bd221d9 powerpc/kexec_file: Enable early kernel OPAL calls
Kernels built with CONFIG_PPC_EARLY_DEBUG_OPAL enabled expects r8 & r9
to be filled with OPAL base & entry addresses respectively. Setting
these registers allows the kernel to perform OPAL calls before the
device tree is parsed.
