platform/x86: toshiba_haps: Convert ACPI driver to a platform one

In all cases in which a struct acpi_driver is used for binding a driver
to an ACPI device object, a corresponding platform device is created by
the ACPI core and that device is regarded as a proper representation of
underlying hardware.  Accordingly, a struct platform_driver should be
used by driver code to bind to that device.  There are multiple reasons
why drivers should not bind directly to ACPI device objects [1].

Overall, it is better to bind drivers to platform devices than to their
ACPI companions, so convert the Toshiba HDD Active Protection Sensor
driver from an ACPI driver to a platform one.

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

Note that the sysfs attributes in haps_attr_group will still be there
in the sysfs directory of the ACPI companion of the platform device
used for driver binding in case there are tools in user space expecting
them to be present there.
