ARM: tegra: cardhu: add dt entry for fixed regulators 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.
