hwmon: (it87) Remove tests nolonger required

Browse Source 
Remove DMI tests for boards that are known to have issues with entering
configuration mode, as now we are testing the chips directly and no
longer need to rely on matching the board.

Leave the DMI table in place, for the nVIDIA board, and any future
expansions.

/*
* On various Gigabyte AM4 boards (AB350, AX370), the second Super-IO chip
* (IT8792E) needs to be in configuration mode before accessing the first
* due to a bug in IT8792E which otherwise results in LPC bus access errors.
* This needs to be done before accessing the first Super-IO chip since
* the second chip may have been accessed prior to loading this driver.
*
* The problem is also reported to affect IT8795E, which is used on X299 boards
* and has the same chip ID as IT8792E (0x8733). It also appears to affect
* systems with IT8790E, which is used on some Z97X-Gaming boards as well as
* Z87X-OC.
* DMI entries for those systems will be added as they become available and
* as the problem is confirmed to affect those boards.
