stm32: stm32f7: add spl build support
This commit supports booting from stm32 internal nor flash. spl U-Boot
initializes the sdram memory, copies next image (e.g. standard U-Boot)
to sdram & then jumps to entry point.
Here are the flash memory addresses for U-Boot-spl & standard U-Boot:
- spl U-Boot : 0x0800_0000
- standard U-Boot : 0x0800_8000
To compile u-boot without spl: Remove SUPPORT_SPL configuration
