Compiler error BTT EBB36 V1.0

[Iskaroth]

Compiling the firmware for the Bigtreetch EBB36 gave me this compiler errror:
src/stm32/can.c: In function 'can_init':
src/stm32/can.c:259:21: error: 'GPIO_Rx' undeclared (first use in this function); did you mean 'GPIOD'?
gpio_peripheral(GPIO_Rx, CAN_FUNCTION, 1);
^~~~~~~

src/stm32/can.c:259:21: note: each undeclared identifier is reported only once for each function it appears in
src/stm32/can.c:260:21: error: 'GPIO_Tx' undeclared (first use in this function); did you mean 'GPIOD'?
