Simplify the build target name.

Currently images are named after
u-boot-${MV_OUTPUT}_$(MV_DDR_FREQ)_$(DDR_TYPE)_$(FLASH_TYPE).bin.
Whenever we change the DDR_FREQ or DDR_TYPE, the target image will be
renamed. It would be simple and consistent for installation program to
pick up the same name regardless of the name changes in uboot build.
Thus, the target images are consolidated to

u-boot.bin (no header)
u-boot-spi.bin (spi flash)
u-boot-nor.bin (nor flash)
u-boot-nand.bin (nand flash)
u-boot-uart.bin (uart recovery)

This implementation basically creates the soft link to those files.
