[U-Boot] [PATCH V4 01/32] arm: imx: Rework i.MX specific commands to be excluded from SPL

[Peng Fan]

From: Tom Rini <trini at konsulko.com>

The "clocks" and "bootaux" commands are only usable in full U-Boot, not
SPL, so do not link them inside of SPL.  Rework a little of the bootaux
related code to make use of __weak and declare parts of it static as
it's local to the file.
