[U-Boot] [PATCH 02/13 v3] arm: at91: spl_at91.c: Call spl_early_init() if OF_CONTROL is enabled

[Stefan Roese <sr@denx.de>]

This patch adds a call to spl_early_init() to board_init_f() which is
needed when CONFIG_SPL_OF_CONTROL is configured. This is necessary for
the early SPL setup including the DTB setup for later usage.

Please note that this call might also be needed for non SPL_OF_CONTROL
board, like the smartweb target. But smartweb fails to build with this
call because its binary grows too big. So I disabled it for these kind
of targets for now.
