kernel: make kmod-ata-core selected by dependent modules

Currently kmod-ata-* will not get into images unless kmod-ata-core is added to
DEVICE_PACKAGES as well. By changing the dependencies from "depends on" to
"select", we do not have the issue anymore.

Furthermore, we can remove most occurrences of the package from DEVICE_PACKAGES
and similar variables, as it is now pulled by dependent modules such as:
- kmod-ata-ahci
- kmod-ata-ahci-mtk
- kmod-ata-sunxi

While at it, use AddDepends/ata for kmod-ata-pdc202xx-old.
