GPIO0_B7 is routed to TXI of the on-board CAN transceiver. The line has a pull-down per SoC default. This means the CAN transceiver transmits a dominant zero and blocks the CAN bus until Linux boots and reconfigures the pin. Let's switch to pull-up as soon as we can (i.e. in SPL). This cuts down the "bus is blocked" time from 10 seconds to < 1 second. Of course, to this needs CONFIG_SPL_BOARD_INIT, so enable it the Jaguar defconfig.
