Enable Erratum 430973 similar to commit 5c86c5339c56 ("ARM:
omap2plus_defconfig: Enable ARM erratum 430973 for omap3") - Since
multiple defconfigs can exist from various points of view (multi_v7,
omap2plus etc.. it is always better to enable the erratum from the
Kconfig selection point of view so that downstream kernels dont have
to rediscover this all over again.

This should safe to select now. Note that proc-v7.S still does not
do anything with multiarch to configure it. So the bootloader still
needs to enable it, or it needs to be done in the machine init like
n900 does.

mh I totally forgot about 430973. I still think [0] is the
better solution. IIRC I never uploaded them to Russel's
patchsystem, though :(

[0] http://comments.gmane.org/gmane.linux.kernel/2002603

So applying into omap-for-v4.7/fixes as it can solve some mysterious
app crashers with armhf at least.

Only on N900 though:

$ git grep ARM_ERRATA_430973
arch/arm/Kconfig:config ARM_ERRATA_430973
arch/arm/configs/axm55xx_defconfig:CONFIG_ARM_ERRATA_430973=y
arch/arm/configs/omap2plus_defconfig:CONFIG_ARM_ERRATA_430973=y
arch/arm/mach-omap2/board-rx51.c:#ifdef CONFIG_ARM_ERRATA_430973
arch/arm/mach-omap2/pdata-quirks.c: if (IS_ENABLED(CONFIG_ARM_ERRATA_430973)) {
arch/arm/mm/proc-v7.S:#if defined(CONFIG_ARM_ERRATA_430973) && !defined(CONFIG_ARCH_MULTIPLATFORM)
