Code to increase CPU frequency goes ahead even in the case the regulator has failed to increase the voltage. This leads to hard error since lower voltages cannot support increased frequency. Prevent this by not increasing frequency in case increasing voltage is not successful. Also, do not lower the voltage if changing the cpu frequency has failed for some reason. Note that we do not return error on failure to decrease voltage as that is not a hard error. Build fix for non-cpufreq kernels by Caglar Akyuz.

Since this capability is useful both from NOR and NAND flashes, it is provided as a new interface and in a file of its own. AEMIF timing configuration is required in cases: 1) Where the AEMIF clock rate can change at runtime (a side affect of cpu frequency change). 2) Where U-Boot does not support NAND/NOR but supports other media like SPI Flash or MMC/SD and thus does not care about setting up the AEMIF timing for kernel to use. 3) Where U-Boot just hasn't configured the timing values and cannot be upgraded because the box is already in the field.

Earlier, AEMIF configuration was being done as a special case for DM644x board, but now more boards emerge which have capability to boot for other media (SPI flash, NOR flash) and have the kernel access NAND flash. This means that kernel cannot always depend on the bootloader to setup the NAND. Also, on platforms such as da850/omap-l138, the aemif input frequency changes as cpu frequency changes; necessiating re-calculation of timimg values as part of cpufreq transtitions. This patch forms the basis for adding that support.
