tegra: pinmux: fix FUNCMUX_NDFLASH_KBC_8_BIT

Even the 8-bit case needs KBCB configured, as pin D7 is located in this
pingroup.

Please note that pingroup ATC seems to come out of reset with its
config set to NAND so one needs to explicitly configure some other
function to this group in order to avoid clashing settings which is
outside the scope of this patch.
