Subject: [PATCH] ARM: tegra: Enable CROS_EC_PROTO for ChromeOS EC mfd driver

The ChromeOS mfd driver (MFD_CROS_EC) select the CROS_EC_PROTO config
symbol because the driver uses some communication helper functions in
drivers/platform/chrome/cros_ec_proto.c but other drivers depends on
CROS_EC_PROTO instead. Mixing select and depends can lead to circular
Kconfig dependencies so the MFD_CROS_EC select should be changed to a
depends on CROS_EC_PROTO instead.

But doing so will break git bisect-ability since MFD_CROS_EC will not
be enabled anymore unless the default configs first explicitly enable
the CROS_EC_PROTO dependency.

Also enable CHROME_PLATFORMS since the CROS_EC_PROTO symbol is inside
that submenu.
