* fix(uavcan): report FlexCAN bus state and error counters on SocketCAN The SocketCAN platform driver returned 0 from getErrorCount(), getRxQueueOverflowCount() and isInBusOffState(), so a controller sitting error-passive or bus-off was invisible from `uavcan status` and the can_interface_status topic on every i.MX RT board. Read them through NuttX's SIOCGCANERRORS instead, and print fault confinement, TEC/REC and RX overruns per interface. Builds without the ioctl keep the old zeros. * fix(uavcan): apply UAVCAN_BITRATE on SocketCAN CanDriver::init() ignored its bitrate argument, so the controller stayed at the Kconfig rate and a bus configured for anything but 1 Mbit/s never came up. Program the nominal rate through SIOCSCANBITRATE when it differs from what the driver reports, keeping the data-phase settings untouched. The driver applies the timing at the next ifup, so the interface is taken down around the request. Older PX4/NuttX restarted a running controller from inside the ioctl instead, which on FlexCAN with ECC RAM initialisation is a bus fault; against that NuttX the rate is left as configured with a warning. * fix(boards): switch SocketCAN defconfigs to NETDEV_CAN_IOCTL PX4/NuttX#401 merges the per-command CAN ioctl options into a single NETDEV_CAN_IOCTL, so the old BITRATE/FILTER/ERROR names no longer exist there and would be silently dropped, disabling the whole CAN ioctl block. Requires the NuttX gitlink to include PX4/NuttX#401; until that bump the option is dropped against the old tree and the bitrate/error ioctls are inert at runtime (the code builds either way). mr-canhubk3 is included so its bitrate ioctl survives the bump.

Also includes PX4/NuttX#399 (STM32F412VG/CG chip selections), which landed between main's gitlink and #401.
