configs: define CONFIG_SPL_SIZE_LIMIT
A new configuration variable CONFIG_SPL_SIZE_LIMIT is introduced to define
the board specific maximum size for the SPL file.
Use Makefile function size_check() to implement the test.
Depending on the size of CONFIG_SPL_SIZE_LIMIT an error like the following
is thrown:
spl/u-boot-spl.bin exceeds file size limit:
limit: 30720 bytes
actual: 33426 bytes
excess: 2706 bytes
make: *** [Makefile:1663: spl/u-boot-spl.bin] Error 1
