[U-Boot] [PATCH v3 15/19] spl: Make CONFIG_SPL_FRAMEWORK board_init_f __weak

[Tom Rini <trini@ti.com>]

Some platforms may need to do more than simply call relocate_code prior
to board_init_r, or perhaps perform more work prior to calling
relocate_code.  Make our default weak to allow for this.  Part of this
requires us to add an extern for 'gdata' so that others can also call
relocate_code.
