Switch the arcmsr driver to use pci_alloc_irq_vectors. We need to two
calls to pci_alloc_irq_vectors as arcmsr only supports multiple MSI-X
vectors, but not multiple MSI vectors.
Otherwise this cleans up a lot of cruft and allows to use a common
request_irq loop for irq types, which happens to only iterate over a
single line in the non MSI-X case.

The Type B Adapter teardown does iounmap on pointers subtracted by a
constant offset. Since the offset is in bytes, we need the pointers to
be of type void * not uint32_t * so the subtraction is done in the
correct units and we iounmap the correct area.

- add arcmsr_enable_eoi_mode()and readl(reg->iop2drv_doorbell_reg) in
arcmsr_handle_hbb_isr() on adapter Type B in case of the doorbell
interrupt clearance is cached
- add conditional declaration for arcmsr_pci_error_detected() and
arcmsr_pci_slot_reset
- check if the sg list member number exceeds arcmsr default limit in
arcmsr_build_ccb()
- change the returned value type of arcmsr_build_ccb()from "void" to
"int" returns FAILED in arcmsr_queue_command()
- modify arcmsr_drain_donequeue() to ignore unknown command and let
kernel process command timeout. This could handle IO request violating
maximum segments, i.e. Linux XFS over DM-CRYPT. Thanks to Milan Broz's
comments <mbroz@redhat.com>
