arm/arm64: defconfig: Update configs to use the new CROS_EC options

Commit Message

Recently we refactored the CrOS EC drivers moving part of the code from
the MFD subsystem to the platform chrome subsystem. During this change
we needed to rename some config options, so, update the defconfigs
accordingly.

Dear all,

This is basically a resend of [1] in order to get patch into the arm-soc
patchwork and can be merged independently of the series. The patch was
originally sent as part of the these series [2] but as defconfig changes
often cause merge conflicts the maintainers prefer to have this merged
through the arm-soc tree. My bad was not including the soc ML from the
begining, so sorry about that.

Thanks,
 Enric

Can we make the entries in the generic arm64 defconfig modules?

Good idea.

Actually I would prefer to have all of them as modules for consistency,
if at all possible.

It is very common boot Chromebooks from an USB device, the EC needs to be
built-in in order to boot from these devices, otherwise you should use an
initramfs. I'd like to avoid forcing people to build an initramfs just to boot
from these devices if possible, in fact, my usual workflow is without initramfs,
and knowing that with the default defconfig just should boot helps a lot sometimes.

Note that, it's not the case for EC subdevices, these are already build as modules.

BTW, Lee asked if this patch should be squashed with the patches that really
renames the config options to help bisect ability, I don't have a hard opinion
as I don't usually run the config option between bisection steps, so please let
me know what do you prefer and I'll respin the patches ASAP if that's the case.

Thanks,
Enric

Ok, fair enough, let's leave it built-in then.

I'm not usually worried about bisection in defconfig changes, since like you
say most commonly one would not run 'make defconfig' betweens the
bisection steps.

If we really care about it, we could keep a symbol like this
in drivers/platform/chrome/Kconfig for one release:

config CONFIG_MFD_CROS_EC
        tristate "Enable ChromeOS Embedded Controller"
        select CROS_EC
        select CHROME_PLATFORMS
        select CONFIG_MFD_CROS_EC_DEV
        help
           This is a transitional Kconfig option and will be removed
           after everyone enables the parts individually.

Not sure if really makes sense do this and tbh and don't have a hard opinion, so
I'll let the final decision to the soc/mfd maintainers. Just let me know and
I'll respin the patches with that if you really want.
