Bigtreetech SKR Pro 1.1/1.2: undefined reference to `board_init'

Issue: Compiling grblHAL for Bigtreetech SKR Pro 1.1/1.2 Board

I'm trying to compile grblHAL for the Bigtreetech SKR Pro 1.1 or 1.2 board using STM32Cube with the following parameters:

Symbol	Value
_USE_IOCTL	1
_USE_WRITE	1
_VOLUMES	1
BOARD_BTT_SKR_PRO_1_2	1
ESTOP_ENABLE	0
HAS_BOOTLOADER
HSE_VALUE	8000000
OVERRIDE_MY_MACHINE
PROBE_ENABLE	0
STM32F407xx
TRINAMIC_ENABLE	2130
TRINAMIC_R_SENSE	110
USB_SERIAL_CDC
USE_HAL_DRIVER
Y_AUTO_SQUARE	1
Y_GANGED	1

I am encountering the following error:

driver.c:(.text.driver_init+0x446): undefined reference to `board_init`

It seems that the board_init function has not been defined for these boards. I noticed that some boards have a "board.c" file in addition to the "board.map" file, but the SKR Pro 1.1 and 1.2 do not have one.

For example, the board defined in longboard32_map.h has the following code in longboard32.c:

#include "driver.h"

#if defined(BOARD_LONGBOARD32)

extern void tmc_spi_init (void);

void board_init (void)
{
#if TRINAMIC_ENABLE
    tmc_spi_init();
#endif
}

Could I use a similar solution for the SKR Pro 1.1/1.2? Would the code be the same?

Fix commited, the code is basically the same for as for the Longboard but since the Longboard code will be expanded I added it as shared code to tmc_spi.c instead.
