This AT91 specific Kconfig option removed the code that dealt with programmable clocks. Each AT91 SoC embeds programmable clocks and there is little gain to remove this code in case that such a clock is not used. If this option is not selected, it causes certain drivers to fail to build. We simply remove this option instead of adding code just to build a workaround.
