Gotos makes a little harder to check the code. In this
particular case, the goto is doing nothing but jumping into
a return.
Instead, just replace the goto by the return, making it
simpler.

Current code assigns 0 to variable 'err', which makes mantis_dma_init()
to return success even if mantis_alloc_buffers() fails.
Fix it by checking the return value from mantis_alloc_buffers() and
propagating it in the case of error.

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.

The remaining dvb drivers are pci, so rename them to match the
bus.
