This fixes up all of the smaller arches that had __dev* markings for their platform-specific drivers. CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

* We need to avoid collisions with `mirrored' VGA ports

* and other strange ISA hardware, so we always want the
|
|
* addresses to be allocated in the 0x000-0x0ff region
|
|
* modulo 0x400.
|
|

|
|
* Why? Because some silly external IO cards only decode
|
|
* the low 10 bits of the IO address. The 0x00-0xff region
|
|
* is reserved for motherboard devices that decode all 16
|
|
* bits, so it's ok to allocate at, say, 0x2800-0x28ff,
|
|
* but we want to try to avoid allocating at 0x2900-0x2bff
|
|
* which might be mirrored at 0x0100-0x03ff..
