Requirements

 1.Add SD card to simulate eeprom to store data drive file .

Description

 1.Add sd card to simulate eeprom driver
 2.Modify SKR Pro V1.1 pin file, support SRAM, Flash, SD card simulation Eeprom storage data, three options
 3.If there is not perfect place, can help optimize, thank you

Benefits

I think you should apply #14809 to this PR

#define HAL_STM32F4_EEPROM_SIZE (E2END + 1) // 16KB

#define _ALIGN(x) attribute ((aligned(x))) // SDIO uint32_t* compat.
static char _ALIGN(4) HAL_eeprom_data[HAL_STM32F4_EEPROM_SIZE];
@tpruvot You should fix this

done, in PR #14844 ... the alignment is for the SDIO transferts, but unsure the STM32 has ported it...

It seems that in the latest firmware, stm32f103xxx chip board, using SD to simulate EEPROM seems to have a bug, that is, it needs to create a new EEPROM.DAT file in SD card first.But there is nothing wrong with the previous download. I am not sure what changes you have made
