package/freescale-imx: move DDR FW choice down to firmware-imx package

The DDR FW along with all other FW code that need to be used in
bootloader or installed on target are related to the firmware-imx
package.

This patch does this job as well as fixing the conjugation of NEED*s*
in the symbol name. Also take advantage of this patch to make the DDR
FW dependant on BR2_PACKAGE_FIRMWARE_IMX.

In addition, the BR2_PACKAGE_FIRMWARE_DDRFW_* option was incorrect, as
there is no package matching this name. So we rename them to
BR2_PACKAGE_FIRMWARE_IMX_*, and add the appropriate Config.in.legacy
handling.
