Subject: [PATCH -next] platform/chrome: Fix Kconfig dependencies for wilco_ec

In the initial version of the Wilco EC Driver, the
dependency order was wrong. It before was possible to
select CONFIG_WILCO_EC and CONFIG_CROS_EC_LPC without
having CONFIG_CROS_EC_LPC_MEC. This was wrong, since
WILCO_EC depends upon CONFIG CROS_EC_LPC_MEC, not the
other way around.

Fixes: 1733c32834e5d1 ("platform/chrome: Add new driver for Wilco EC")
