[ALSA] caiaq - misc input handling fixes
- link input device with its parent so that it placed in proper spot
in sysfs hierarchy
- drivers that allow changing their keymaps should use private copy
of the keymap so that one instance of a device does not affect
another instance
- it is preferred for drivers to properly set up input_dev->phys to
help userspace locate devices
- drivers should use usb_to_input_id(), or perform endianess conversion,
themselves, otherwise ID is not correct on big-endian boxes
- whitespace and formatting cleanup
