MLK-11364 imx: mx6ul : Add support for i.MX6UL 9x9 EVK board

The i.mx6ul 9x9 EVK shares the same base board with 6ul 14x14 EVK
with two main changes on CPU board:
1. Change to use pfuze 3000.
2. Use 256MB LPDDR2 memory.

This patch uses a macro CONFIG_6UL_9X9_LPDDR2 to distinguish the changes above,
basing on 14x14 EVK board level codes.

The new build target for the 9x9 EVK:  mx6ul_9x9_evk_config
