[PATCH 4.19 020/190] powerpc/64: mark start_here_multiplatform as __ref

[ Upstream commit 9c4e4c90ec24652921e31e9551fcaedc26eec86d ]

Otherwise, the following warning is encountered:

WARNING: vmlinux.o(.text+0x3dc6): Section mismatch in reference from the variable start_here_multiplatform to the function .init.text:.early_setup()
The function start_here_multiplatform() references
the function __init .early_setup().
This is often because start_here_multiplatform lacks a __init
annotation or the annotation of .early_setup is wrong.
