Revert "Kernel/AHCI: Add a boot argument to force AHCI to operate on IRQ 11"

Browse source 
This reverts commit cfc2f33dcb.

We can't actually change the IRQ line value and expect the device
to work with it (this was my mistake).
That register is R/W so the firmware can figure out IRQ routing and put
the correct value and write it to the Interrupt line register.
