powerpc/fadump: Fix section mismatch warning

With some compilers/configs fadump_setup_param_area() isn't inlined into
its caller (which is __init), leading to a section mismatch warning:

  WARNING: modpost: vmlinux: section mismatch in reference:
  fadump_setup_param_area+0x200 (section: .text.fadump_setup_param_area)
  -> memblock_phys_alloc_range (section: .init.text)

Fix it by adding an __init annotation.
