NVIDIA's Tegra114 SoCs have the matrix keyboard controller which

Add DT entry for KBC controller with compatibility as "nvidia,tegra114-kbc",
"nvidia,tegra20-kbc".
I thought the HW really wasn't compatible with Tegra20 due to the
reduced number of rows/columns/pins supported?

Hw controller is really compatible. Only thing is that there is no physical pins on SoC for KBC-ROW11 to KBC-ROW15.
Because, there is no physical pins for ROW11 to ROW15, we asked to remove programming/reference this rows from TRM of T114 to consistent with SoCs.
