[PATCH 1/4] staging: vc04_services: avoid the use of typedef for function pointers

[Gaston Gonzalez]

Replace typedefs bcm2835_audio_newpcm_func and bcm2835_audio_newctl_func
with equivalent declarations to better align with the linux kernel
coding style.

As the '_func' in the function names is somehow reduntant, it was
dropped in favour of the shorter names: 'bcm2835_audio_newpcm' and
'bcm2835_audio_newctl'
