[PATCH 1/1] Input: elantech: Use SMBus based on bus info

There are some new HP laptops with Elantech touchpad don't support multitouch. Both ETP_BUS_SMB_HST_NTFY_ONLY and ETP_BUS_PS2_SMB_HST_NTFY devices can use SMBus to support 5 fingers touch, so we need to chech them too. So use elantech_use_host_notify() to do a more thouroughly check.
