media: av7110: don't do float point math
It sounds that earlier versions of GCC have troubles when
doing const math at compile time, if no typecast is used:
on i386:
ERROR: modpost: "__floatunsidf" [drivers/media/pci/ttpci/dvb-ttpci.ko] undefined!
ERROR: modpost: "__ltdf2" [drivers/media/pci/ttpci/dvb-ttpci.ko] undefined!
The warning was generated on gcc (SUSE Linux) 7.5.0.
Gcc 9.2 compiles it fine.
As an added bonus, it also fixes this objtool warning:
drivers/media/pci/ttpci/av7110_v4l.c:163:11: error: SSE register return with SSE disabled
