ibft: Expose iBFT acpi header via sysfs

Some ethernet adapter vendors are supplying products which support optional
(payed license) features. On some adapters this includes a hardware iscsi
initiator. The same adapters in a normal (no extra licenses) mode of
operation can be used as a software iscsi initiator. In addition, software
iscsi boot initiators are becoming a standard part of many vendors uefi
implementations. This is creating difficulties during early boot/install
determining the proper configuration method for these adapters when they
are used as a boot device.

The attached patch creates sysfs entries to expose information from the
acpi header of the ibft table. This information allows for a method to
easily determining if an ibft table was created by a ethernet card's
firmware or the system uefi/bios. In the case of a hardware initiator this
information in combination with the pci vendor and device id can be used
to ascertain any vendor specific behaviors that need to be accommodated.

So introduce a new attribute 'prefix-len'.

Some older user-space code might rely on the netmask attribute
being present, so we should always display it.

[SCSI] iscsi_ibft, be2iscsi, iscsi_boot: fix boot kobj data lifetime management

be2iscsi passes the boot functions its phba object which is
allocated in the shost, but iscsi_ibft passes in a object
allocated for each item to display. The problem is that
iscsi_boot_sysfs was managing the lifetime of the object
passed in and doing a kfree on release. This causes a double
free for be2iscsi which frees the shost in its pci_remove.

This patch fixes the problem by adding a release callback
which the drivers can call kfree or a put() type of function
(needed for be2iscsi which will do a get/put on the shost).

ibft: separate ibft parsing from sysfs interface

Not all iscsi drivers support ibft. For drivers like be2iscsi
that do not but are bootable through a vendor firmware specific
format/process this patch moves the sysfs interface from the ibft code
to a lib module. This then allows userspace tools to search for iscsi boot
info in a common place and in a common format.

ibft iscsi boot info is exported in the same place as it was
before: /sys/firmware/ibft.

vendor/fw boot info gets export in /sys/firmware/iscsi_bootX, where X is the
scsi host number of the HBA. Underneath these parent dirs, the
target, ethernet, and initiator dirs are the same as they were before.
