Subject: [PATCH -next] xtensa: Fix fix linker script transformation for .text / .text.fixup

Commit 779c88c94c34 ("ARM: 8321/1: asm-generic: introduce .text.fixup
input section") introduced a new .text.fixup section which is merged
with .text at link time. This causes xtensa builds to fail with lots
of error messages similar to the following.

lib/lib.a(kobject.o): In function `kobject_create':
(.text+0x498): dangerous relocation: l32r: literal placed after use:
				     (.literal+0x150)

Linker script transformation needs to be updated to detect and handle
the new section.

Fixes: 779c88c94c34 ("ARM: 8321/1: asm-generic: introduce .text.fixup
		     input section")
