cpqarray: remove it from the kernel 

We disabled the ability to enable this driver back in October of 2013,
we should be able to safely remove it at this point. The initial goal
was to remove it in 3.15, so now is the time.

This driver is for Compaq's SMART2 Intelligent Disk Array Controllers.
Supported Cards:
----------------
This driver is known to work with the following cards:
* SMART (EISA)
* SMART-2/E (EISA)
* SMART-2/P
* SMART-2DH
* SMART-2SL
* SMART-221
* SMART-3100ES
* SMART-3200
* Integrated Smart Array Controller
* SA 4200
* SA 4250ES
* SA 431
* RAID LC2 Controller
It should also work with some really old Disk array adapters, but I am
unable to test against these cards:
* IDA
* IDA-2
* IAES
EISA Controllers:
-----------------
If you want to use an EISA controller you'll have to supply some
modprobe/lilo parameters. If the driver is compiled into the kernel, must
give it the controller's IO port address at boot time (it is not
necessary to specify the IRQ). For example, if you had two SMART-2/E
controllers, in EISA slots 1 and 2 you'd give it a boot argument like
this:
smart2=0x1000,0x2000
If you were loading the driver as a module, you'd give load it like this:
modprobe cpqarray eisa=0x1000,0x2000
You can use EISA and PCI adapters at the same time.
Device Naming:
--------------
You need some entries in /dev for the ida device. MAKEDEV in the /dev
directory can make device nodes for you automatically. The device setup is
as follows:
Major numbers:
72 ida0
73 ida1
74 ida2
75 ida3
76 ida4
77 ida5
78 ida6
79 ida7
Minor numbers:
b7 b6 b5 b4 b3 b2 b1 b0
|----+----| |----+----|
| |
| +-------- Partition ID (0=wholedev, 1-15 partition)
|
+-------------------- Logical Volume number
The device naming scheme is:
/dev/ida/c0d0 Controller 0, disk 0, whole device
/dev/ida/c0d0p1 Controller 0, disk 0, partition 1
/dev/ida/c0d0p2 Controller 0, disk 0, partition 2
/dev/ida/c0d0p3 Controller 0, disk 0, partition 3
/dev/ida/c1d1 Controller 1, disk 1, whole device
/dev/ida/c1d1p1 Controller 1, disk 1, partition 1
/dev/ida/c1d1p2 Controller 1, disk 1, partition 2
/dev/ida/c1d1p3 Controller 1, disk 1, partition 3
