V4L/DVB: ir-core: centralize sysfs raw decoder enabling/disabling
With the current logic, each raw decoder needs to add a copy of the exact same sysfs code. This is both unnecessary and also means that (re)loading an IR driver after raw decoder modules have been loaded won't work as expected. This patch moves that logic into ir-raw-event and adds a single sysfs file per device. Reading that file returns something like: "rc5 [rc6] nec jvc [sony]" (with enabled protocols in [] brackets) Writing either "+protocol" or "-protocol" to that file will enable or disable the according protocol decoder. An additional benefit is that the disabling of a decoder will be remembered across module removal/insertion so a previously disabled decoder won't suddenly be activated again. The default setting is to enable all decoders. This is also necessary for the next patch which moves even more decoder state into the central raw decoding structs.
