Kernel: Extended IDE interface to allow slave device usage ( #283 )
...
The IDE Disk Controller driver has been extended to allow the secondary device on the channel to be initialised and used. A test as to whether this is working (for anyone interested) is to modify `init.cpp:87` to `auto dev_hd0 = IDEDiskDevice::create(IdeDiskDevice::DeviceType::SLAVE);`. The kernel will fail to boot, as there is no disk attached to CHANNEL 1's slave. This was born out of the fact that my FAT driver can't be tested as easily without creating a partition on `hda`.

AK: Rename the common integer typedefs to make it obvious what they are.
...
These types can be picked up by including <AK/Types.h>:
* u8, u16, u32, u64 (unsigned)
* i8, i16, i32, i64 (signed)

IDEDiskDevice: Implement basic DMA writes.
...
This could share more code with reads, and generally be better. But it works
and it's considerably faster than PIO, so let's use it. :^)

Kernel: Tidy up IDEDiskDevice a bit.
...
The main cleanup here is putting the I/O address base in a member variable.

IDEDiskDevice: Support reading multiple sectors at a time with DMA.
...
This is another sizable improvement to GCC compile times.

IDEDiskDevice: Use wait_for_irq() when waiting for DMA transfers.
...
Also make sure we return any device errors to caller.

IDEDiskDevice: Add support for DMA reads.
...
I've only tested this with the PIIX3 chipset QEMU emulates, but it works
pretty well here. GCC compile times are cut roughly in half :^)

Kernel: Use rep insw/outsw for IDE transfers.

There are much faster ways to do disk transfers, but I'm not implementing
those today. In the meantime, this is slightly nicer. :^)
