This commit moves: CONFIG_OF_CONTROL CONFIG_OF_SEPARATE CONFIG_OF_EMBED CONFIG_OF_HOSTFILE
Because these options are currently not supported for SPL, the "Device Tree Control" menu does not appear in the SPL configuration.
Note: zynq-common.h should be adjusted so as not to change the default value of CONFIG_SPL_FAT_LOAD_PAYLOAD_NAME.

I suggest to use boolean symbols HAS_* or SUPPORTS_* like the kernel does. For example:
config SUPPORTS_OF_CONTROL bool
menu "Device Tree Control" depends on !SPL_BUILD depends on SUPPORTS_OF_CONTROL
arch/Kconfig: config ARM bool "ARM architecture" select SUPPORTS_OF_CONTROL

If this option is enabled, DTB will be read from a file on startup.This is only useful for Sandbox. Use the -d flag to U-Boot tospecify the file to read.+endchoice
