Add preliminary support for boards based on the JZ4755 SoC from Ingenic. It is a low-power SoC with a MIPS32r1 core running at ~432 MHz, and has no FPU. The JZ4755 SoC is supposed to be newer than the JZ4725B SoC, but its internals are very close to each other. Also the Ingenic's kernel source tree calls JZ4755 as JZ4750D and JZ4725B as JZ4750L, this might mean that JZ4725B is a pin to pin compatible replacement for older JZ4725 (both are LQFP128) but belongs to newer generation JZ475x. Who knows? I guess Ingenic released their SoCs in the following order: JZ4720 (MXU ?) JZ4725 (MXU ?) JZ4730 (MXU ?) JZ4740 (MXU1 r1) JZ4750 (MXU1 r2) JZ4755 (MXU1 r2) JZ4725b (MXU1 r2) JZ4760 ... So JZ4755 DT is reusing many JZ4725B drivers because their support in mainline kernel appears earlier.
