Input: elantech - fix protocol errors for some trackpoints in SMBus mode
There are some version of Elan trackpads that send incorrect data when
in SMbus mode, unless they are switched to use 0x5f reports instead of
standard 0x5e. This patch implements querying device to retrieve chips
identifying data, and switching it, when needed to the alternative
report.
