[PATCH 01/17] ARM: i.MX: boot: Coalesce copy-pasted code

[Andrey Smirnov <andrew.smirnov@gmail.com>]

All of the instances of imx*_boot_save_loc() do exactly the same thing with
the only difference being SoC-specific imx*_get_boot_source
call. Convert the code into a generic function taking function pointer
+ a macro to take care of the boilerplate.
