x86/ioremap: Simplify setup_data mapping variants

Browse source

memremap_is_setup_data() and early_memremap_is_setup_data() share
completely the same process and handling, except for the differing
memremap/unmap invocations.

Add a helper __memremap_is_setup_data() extracting the common part and
simplify a lot of code while at it.

Mark __memremap_is_setup_data() as __ref to suppress this section
mismatch warning:

  WARNING: modpost: vmlinux: section mismatch in reference: __memremap_is_setup_data+0x5f (section: .text) ->
  early_memunmap (section: .init.text)
