Write ata_lba_read routine to load 100 disk sectors from the disk into
memory address 0x00100000 (1MiB).
Once the data is loaded, jump to that Address

Move the code unders [BITS 32] label to its own file to be loaded as a
kernel by the boot loader.
Add a linker script to link the bootloader and the kernel in a single
binary file.
Add a build script to make it easier to use the cross compiler
Update the Makefile to build everything and pack it into the os.bin

Create a GDT table and use it to switch
CPU into protected mode.
This also gets rid of the print routines. Giving
we won't have access to the BIOS interrupts once
we switch the CPU to protected mode, they are pointless.

Remove interrupt table setup and testing, IRQs will be added later
on an interrupt descriptor table.
For some reason once the exception is handled, the disk read fails,
so just remove it for now
