Cadhu have multiple power rails which are controlled by GPIOs. Add support of these power rail control through fixed regulators. Add entry for all fixed regulators for cardhu-a02 and a04. The details are taken from downstream kernel. Some points on this change are: * Add the tps65910-LDO5 entry and make it always ON to supply power to SDMMC. Once the sd driver support regulator handling, this flag will be remove. * Dropping registration of rail vdd_sdmmc1 as the gpio is used by sdhci power-gpio. This need to fix in sdhci driver and then need to add the registration mechanism. Just removing power-gpio and adding fixed regulator with this gpio is causing the sd access to fail because first probe call of this regulator fails due to non-available of parent and so it calls gpio_free() which disable the pins in gpio mode make pin output to LOW causes power to OFF. In probe retry, it got success and it powered-on but it again need to do again numeration of card here.
