android/native/jni/input_android.c:

- Fixed off-by-one when using g_settings.input.icade_count to index in array of icade profiles. It has just been incremented...
- Added setting actual device names instead of generic "Broadcom Bluetooth HID" so the libretro menu shows it. Also added a bit of logging when detecting generic devices and selecting an icade profile.
- Fixed some wrong button assignments for iPega controller.
- Added a note about the dpad buttons not working, it's the next thing I want to fix.

android/phoenix/res/xml/prefs.xml:

- Fixed key names for icade profiles, input_autodetect_icade_profile_pad0 does not exist in the config as given in the root settings.c file, they start at 1.
