[U-Boot] [PATCH v5 3/7] env: Enable getenv_f() for SPL_BUILD

[Stefan Roese]

With this patch, getenv_f() can be included easily into the SPL
binary. With this, SPL boards can now use getenv_f() to read
environment variables (e.g. to detect if the OS or U-Boot shall
be executed).

In the approach this is done for env stored in NOR flash, as this
will be used by an upcoming MPC5200 board port.

Changes in v4:
- getenv_f not extracted into separate file. Only Makefile
  additions for SPL_BUILD needed.

Changes in v3:
- Rebased on current master plus SPL framework v7
