Kernel/Storage: Remove ATA IDE support

Nobody uses this functionality. I used this code on my old 2007 ICH7
test machine about a year ago, but bare metal is a small aspect of the
project, so it's safe to assume that nobody really tests this piece of
code.
Therefore, let's drop this for good and focus on more modern hardware.
