Kernel/Storage: Don't try to enumerate PCI adapters if PCI is disabled

If there's no PCI bus, then it's safe to assume that we run on a x86
machine that has an ISA IDE controller in the system. In such case, we
just instantiate a ISAIDEController object that assumes fixed locations
of IDE IO ports.

Kernel: Remove the kmalloc_eternal heap :^)

This was a premature optimization from the early days of SerenityOS.
The eternal heap was a simple bump pointer allocator over a static
byte array. My original idea was to avoid heap fragmentation and improve
data locality, but both ideas were rooted in cargo culting, not data.

We would reserve 4 MiB at boot and only ended up using ~256 KiB, wasting
the rest.

This patch replaces all kmalloc_eternal() usage by regular kmalloc().

Kernel/Storage: Move all ATA related code to a new subdirectory

Like what happened with the PCI and USB code, this feels like the right
thing to do because we can improve on the ATA capabilities and keep it
distinguished from the rest of the subsystem.
