media: dvb-frontends: add ST STV0910 DVB-S/S2 demodulator frontend driver This adds a multi frontend driver for the ST STV0910 DVB-S/S2 demodulator frontends. The driver code originates from the Digital Devices' dddvb vendor driver package as of version 0.9.29, and has been cleaned up from core API usage which isn't supported yet in the kernel, and additionally all obvious style issues have been resolved. All camel case and allcaps have been converted to kernel_case and lowercase. Patches have been sent to the vendor package maintainers to fix this aswell. Signal statistics acquisition has been refactored to comply with standards. Permission to reuse and mainline the driver code was formally granted by Ralph Metzler <rjkm@metzlerbros.de>.
