Let Kconfig handle lis3lv02d dependencies

The dependencies between the various lis3lv02d drivers make it
impossible to split them to different directories, while we really
want to do this. Move handling of dependencies from Makefile to
Kconfig, to make the move possible at all.

-         This driver provides support for the LIS3* accelerometers, such as the
-         LIS3LV02DL or the LIS331DL. In particular, it can be found in a number
-         of HP laptops, which have the "Mobile Data Protection System 3D" or
-         "3D DriveGuard" feature. On such systems the driver should load
-         automatically (via ACPI alias). The accelerometer might also be found
-         in other systems, connected via SPI or I2C. The accelerometer data is
-         readable via /sys/devices/platform/lis3lv02d.

-         This driver also provides an absolute input class device, allowing
-         a laptop to act as a pinball machine-esque joystick. It provides also
-         a misc device which can be used to detect free-fall. On HP laptops,
-         if the led infrastructure is activated, support for a led indicating
-         disk protection will be provided as hp::hddprotect. For more
-         information on the feature, refer to Documentation/hwmon/lis3lv02d.
