Subject: [PATCH 4.19 032/306] powerpc/boot: Fix opal console in boot wrapper

From: Joel Stanley <joel@....id.au>

[ Upstream commit 1a855eaccf353f7ed1d51a3d4b3af727ccbd81ca ]

As of commit 10c77dba40ff ("powerpc/boot: Fix build failure in 32-bit
boot wrapper") the opal code is hidden behind CONFIG_PPC64_BOOT_WRAPPER,
but the boot wrapper avoids include/linux, so it does not get the normal
Kconfig flags.

We can drop the guard entirely as in commit f8e8e69cea49 ("powerpc/boot:
Only build OPAL code when necessary") the makefile only includes opal.c
in the build if CONFIG_PPC64_BOOT_WRAPPER is set.

Fixes: 10c77dba40ff ("powerpc/boot: Fix build failure in 32-bit boot wrapper")
