Weak symbols don't work as expected when you want to override them from within the same static library. This patch changes the arch_ndelay() function so that instead of having a weak generic implementation, the choice between generic implementation and an arch-specific override is explicitly made by Kconfig. Let's also drop the "arch_" prefix and just call this ndelay().
