Replace the older style one-element array with a flexible array member.
There does not seem to be any allocation for this struct in the code, so
no more code changes are required.

The following cocci warning is fixed:
drivers/media/dvb-frontends/mxl5xx_defs.h:182:4-8: WARNING use flexible-array member instead (https://www.kernel.org/doc/html/latest/process/deprecated.html#zero-length-and-one-element-arrays)

While this patch looks good to me, I'll skip it until my comment for the
previous patch is addressed. Actually, I think the two patches should be
combined, but I leave that up to you.
