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

Browse source 
As a compromise, if the fimrware decided to set the IRQ line to be 7,
or something else we can't deal with, the user can simply force the code
to work with IRQ 11, with the boot argument "force_ahci_irq_11" being
set to "on".
