Subject: [PATCH 5.4 39/43] MIPS: fix build with gcc-12

From: Sudip Mukherjee <sudipm.mukherjee@...il.com>

Some mips builds with gcc-12 fails with the error:
arch/mips/jz4740/setup.c:64:25: error: comparison between two arrays
	[-Werror=array-compare]
   	64 |         if (__dtb_start != __dtb_end)

'd24f48767d5e ("MIPS: Use address-of operator on section symbols")' has
been applied which fixes most of the error, but it missed one file which
was not available upstream when the change was done.

Fixes: d24f48767d5e ("MIPS: Use address-of operator on section symbols")
