Laxman Dewangan fa4a925230 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.

/**
* This file contains common DT entry for all fab version of Cardhu.
* There is multiple fab version of Cardhu starting from A01 to A07.
* Cardhu fab version A01 and A03 are not supported. Cardhu fab version
* A02 will have different sets of GPIOs for fixed regulator compare to
* Cardhu fab version A04. The Cardhu fab version A05, A06, A07 are
* compatible with fab version A04. Based on Cardhu fab version, the
* related dts file need to be chosen like for Cardhu fab version A02,
* use tegra30-cardhu-a02.dts, Cardhu fab version A04 and later, use
* tegra30-cardhu-a04.dts.
* The identification of board is done in two ways, by looking the sticker
* on PCB and by reading board id eeprom.
* The stciker will have number like 600-81291-1000-002 C.3. In this 4th
* number is the fab version like here it is 002 and hence fab version A02.
* The (downstream internal) U-Boot of Cardhu display the board-id as
* follows:
* BoardID: 0C5B, SKU: 0A01, Fab: 02, Rev: 45.00
* In this Fab version is 02 i.e. A02.
* The BoardID I2C eeprom is interfaced through i2c5 (pwr_i2c address 0x56).
* The location 0x8 of this eeprom contains the Fab version. It is 1 byte
* wide.
