media: dvb-frontends/stv{0910,6111}: constify tables
Mark lookup tables and fe_ops things const so the compiler can put them into .rodata. While at it, improve name and identifier strings (moddesc, fe_ops). Signed-off-by: Daniel Scheller <d.scheller@gmx.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
