v1[1] was an out-of-date patch that used the old slave-reg property to define
the device address in the LPC IO space. In v2 of the driver series[2] we agreed
to make the property aspeed-specific on the back some quirks of the hardware.

v2 of this patch updates the tiogapass dts to use the upstream
'aspeed,lpc-io-reg' property instead of 'slave-reg'. I discovered the mismatch
when I started to tidy up the various branches I have lying around for the
ASPEED DT cleanups.
