linux: Allow for more i2c buses

Similar to commit df79893, this allows klipper to use up to /dev/i2c-14. Similar to before, this limit is arbitrary. This is required for some other SoCs, which have even more i2c buses available, e.g. the rk3399: $ ls -1 /dev/i2c-* /dev/i2c-0 /dev/i2c-3 /dev/i2c-7 Signed-off-by: Carl Richard Theodor Schneider <[email protected]>
