I wonder if there will be problems with this patch; the loop in
tegra_kbc_report_keys() is going to process 8 bits more of the last
register and the loop in tegra_kbc_config_pins() will now touch one
more row and one more column register. I think these loops should be
limited at run-time based on the SoC actually being executed upon?
