Subject: [PATCH] spl: saveenv: adding saveenv support in SPL

By default saveenv option is not supported for SPL. This patch enable the 
support for save environment variable for SPL build.

Enable save environment support in SPL after setenv. By default the saveenv 
option is not provided in SPL, but some boards need this support in 'Falcon' 
boot, where SPL need to boot from different images based on environment 
variable set by OS. For example OS may set "reboot_image" environment variable 
to "recovery" inorder to boot recovery image by SPL. The SPL read 
"reboot_image" and act accordingly and change the reboot_image to default mode 
using setenv and save the environemnt.

Ok,  will drop SUPPORT and use SPL_SAVEENV.

But I wonder if we could use SPL_SAVEENV, and drop the SUPPORT? For
U-Boot proper we use CONFIG_CMD_SAVEENV which is inconsistent - I
think we should really have a CONFIG_SAVEENV separate from the
command.
