The goal of this patch is to clean up the code related to choosing spl MMC boot mode.

The spl_boot_mode() now is called only in spl_mmc_load_image() function, which is only compiled in if CONFIG_SPL_MMC_SUPPORT is enabled.

To achieve the goal, all per mach/arch implementations eligible for unification has been replaced with one __weak implementation.

--- Comments regarding cleanup (to help maintainers assessment if those changes break anything):

Implementations necessary to stay as is: ---------------------------------------- - SW fix for broken ROM boot code arch/arm/mach-uniphier/mmc-boot-mode.c

- Omap specific adjustments: arch/arm/mach-omap2/boot-common.c

Below archs had a bit off-standard approach, but were eligible for using the __weak function: -------------------- - at91 -> check if proper configs flags in the weak function are set: arch/arm/mach-at91/spl.c

- zyncmp -> the BOOT_DEVICE_RAM return of spl_boot_mode seems like an error (will hang in spl_mmc_load_image() anyway) arch/arm/cpu/armv8/zynqmp/spl.c

- fsl -> here we had a return of BOOT_DEVICE_NAND, but the spl_boot_mode is eMMC/SD card specific (will hang in spl_mmc_load_image() anyway)
