Minor cleanups to the IPMI driver for 5.9 

Nothing of any major consequence.  Duplicate code, some missing \n's in
 sysfs files, some documentation and comment changes.

The addresses are normal I2C addresses. The adapter is the string
name of the adapter, as shown in /sys/class/i2c-adapter/i2c-<n>/name.
@ -537,6 +538,9 @@ The slave_addrs specifies the IPMI address of the local BMC. This is
usually 0x20 and the driver defaults to that, but in case it's not, it
can be specified when the driver starts up.
alerts_broken does not enable SMBus alert for SSIF. Otherwise SMBus
alert will be enabled on supported hardware.
Discovering the IPMI compliant BMC on the SMBus can cause devices on
the I2C bus to fail. The SMBus driver writes a "Get Device ID" IPMI
message as a block write to the I2C bus and waits for a response.
