[PATCH 8/9] HID: intel-ish-hid: Move functions related to bus and device

From: Srinivas Pandruvada
Date: Sun Mar 03 2019 - 11:47:27 EST


Move function idefinitions related to bus and device to common header file.
Also create new function to get fw client id and move ish_hw_reset() from
inline to exported function.
