media: mxl5005s: reduce stack usage in MXL5005_ControlInit

This function initializes two large structures with arrays. On at least
parisc, the specific code sequence here leads to a badly misoptimized
output from the compiler along with a warning about the resulting
excessive stack usage from many spilled variables:

drivers/media/tuners/mxl5005s.c: In function 'MXL5005_ControlInit.isra':
drivers/media/tuners/mxl5005s.c:1660:1: warning: the frame size of 1400 bytes is larger than 1024 bytes [-Wframe-larger-than=]

Splitting this one function into two functions avoids this because there
are few temporaries that can be spilled to the stack in each of the smaller
structures, so this avoids the warning and also improves readability.
