 - Have MODULE_LICENCE("GPL*") inside which was used in the initial

The icside_probe function can be called for hotplugged devices, so
its reference to the __initconst icside_v6_port_info variable
may be invalid, as Kbuild points out:

WARNING: drivers/ide/icside.o(.text+0x338): Section mismatch in reference from the function icside_probe()
 to the (unknown reference) .init.rodata:(unknown)

Interestingly, this problem only shows up with clang but not
with gcc, which optimizes out the __initconst variable.

This removes the incorrect annotation.

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.

The icside driver can be configured without DMA support, but it
doesn't compile then, because DMA operations are referenced.

Fix problem introduced by commit 5e37bdc ("ide: add struct
ide_dma_ops (take 3)"): d.dma_ops shouldn't be cleared if
we are going to use DMA.

Bring back ->maskproc method since it is still needed for proper operation,
as noticed by Russell King:

This patch reverts changes done in commit dff8817 (I became confused due to
non-standard & undocumented ->maskproc method, anyway sorry about that).
