ACPI: EC: Convert the driver to a platform one

Browse source

While binding drivers directly to struct acpi_device objects allows
basic functionality to be provided, at least in the majority of cases,
there are some problems with it, related to general consistency, sysfs
layout, power management operation ordering, and code cleanliness.

Overall, it is better to bind drivers to platform devices than to their
ACPI companions, so convert the ACPI embedded controller (EC) driver
to a platform one.

After this conversion, acpi_bus_register_early_device() does not need
to attempt to bind an ACPI driver to the struct acpi_device created by
it, so update it accordingly.

While this is not expected to alter functionality, it changes sysfs
layout and so it will be visible to user space.
