[PATCHv2 3/9] board: lx2160a: Don't program the GIC RD tables if failed to reserve memory

[Zhiqiang Hou]

From: Hou Zhiqiang <zhiqiang....@nxp.com>

Program the GIC redistributor tables only when succeeded to reserve memory
for them, otherwise kernel will lose the chance to program them using
allocated memory.
