[PATCH 2/3] configs: stm32mp1: Remove misleading CONFIG_SPL_BSS_START_ADDR

> CONFIG_SPL_BSS_START_ADDR is only used on a few mach- linker scripts.
> stm32mp1 uses the generic script under arch/arm/cpu/u-boot-spl.lds,
> which does not make use of this definition.
>
> The SPL BSS starts in SRAM, right after .text, .rodata, .data, and
> .u_boot_list. A very short version of the STM32MP1 memory map is:
> * SYSRAM: 2ffc0000 - 30000000 <- all of SPL is here
> * DRAM: c0000000+
>
> 0xC0200000 is a DRAM address, and has nothing to do with SPL. It is
> just very misleading to have it next to CONFIG_SPL_BSS_MAX_SIZE, or to
> have it at all.
