Kernel: Add support for ATA CHS addressing and cleanup code
...
I thought that I had an PC without LBA support so I implement support
for CHS. Turns out that my ATA device detection was broken and was no
device on that port and initialize data was just garbage.
Now that I added CHS, I guess I should just keep it in :)
Both ATA read and write are now combined into a single function to avoid
code duplication.

Kernel/init: /dev/tty is now custom symlink to controlling terminal
...
kernel now passes the name of default console to init process so init
knows which file to open as stdio. before /dev/tty was referencing the
system wide current terminal which was inherited from cmdline. This
doesn't work anymore as we have pseudo terminals implemented that can
chage the current terminal during runtime :D

I had not understood how MSIs work and I was unnecessarily routing them

Also MSIs were reserving interrupts that IOAPIC was capable of
generating. Now IOAPIC and MSIs use different set of interrupts so
IOAPIC can use more interrupts if needed.
