A major motivation for this cleanup was the fact, that a number of calls of that function resulted in 32 bit wide shift operations on u32 data, which according to the C-ISO/IEC-9899-Standard provokes undefined behaviour: 6.5.7 Bitwise shift operators ... If the value of the right operand is negative or is greater than or equal to the width of the promoted left operand, the behavior is undefined.

Consolidate this to a generic location such that other TI platforms such as BeagleBoard-XM can also use the same. NOTE: at this point in time, I dont yet see a need for a generic dummy ethernet MAC address creation function, but if there is a need in the future, this can be further abstracted out.

Use !CONFIG_SKIP_LOWLEVEL_INIT rather than CONFIG_SPL_BUILD || CONFIG_NOR_BOOT to make the code clearer, and to make supporting XIP QSPI boot clearer in the code.
