media: mantis: fix two smatch errors

Drop two dprintk's that relied on a non-NULL mantis pointer
when it was in fact a NULL pointer.

Fix those warnings:

drivers/media/pci/mantis/mantis_cards.c:73 mantis_irq_handler() error: we previously assumed 'mantis' could be null (see line 72)
drivers/media/pci/mantis/hopper_cards.c:64 hopper_irq_handler() error: we previously assumed 'mantis' could be null (see line 63)

media: drivers: improve a size determination

Replace the specification of a data structure by a pointer dereference
as the parameter for the operator "sizeof" to make the corresponding size
determination a bit safer according to the Linux coding style convention.

This issue was detected by using the Coccinelle software.

[media] mantis: add remote control support

The embedded UART is apparently used to receive decoded IR (RC5?) codes.
Forward these scan codes to the RC framework and (where known) add
corresponding mapping tables to translate them into regular keys.

This patch has been tested on a TechniSat CableStar HD2. The mappings of other
rc-maps were taken from Christoph Pinkl's patch
(http://patchwork.linuxtv.org/patch/7217/) and the s2-liplianin repository. The
major difference to Christoph's patch is a reworked interrupt handling of the
UART because the RX interrupt is apparently level triggered and requires
masking until the FIFO is read by the UART worker.

Drivers: media: remove __dev* attributes.

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.
