b0e6ef4640 dm: i2c: tegra: Convert to driver model
This converts all Tegra boards over to use driver model for I2C. The driver
is adjusted to use driver model and the following obsolete CONFIGs are
removed:

   - CONFIG_SYS_I2C_INIT_BOARD
   - CONFIG_I2C_MULTI_BUS
   - CONFIG_SYS_MAX_I2C_BUS
   - CONFIG_SYS_I2C_SPEED
   - CONFIG_SYS_I2C

This has been tested on:
- trimslice (no I2C)
- beaver
- Jetson-TK1

It has not been tested on Tegra 114 as I don't have that board.

f3e85e4825 twl4030: device-index-specific MMC power initializations, common ramp-up delay
Not every device has multiple MMC slots available, so it makes sense to enable
only the required LDOs for the available slots. Generic code in omap_hsmmc will
enable both VMMC1 and VMMC2, in doubt.

5b471dee99 power_spi.c: Rewrite pmic_reg function

today, cannot be, so remove it.  Integrate the probe function into
pmic_reg as it's not really a "probe" today.  Finally, add an err label

74bf7961a0 sunxi: axp152: dcdc3 scale is 50mV / step not 25mV / step
Currently uboot wrongly uses 25mV / step for dcdc3, this is a copy and paste
error introduced when adding the axp152_mvolt_to_target during review of the
axp152.c driver. This results in u-boot setting Vddr to 2.3V instead of 1.5V.

This commit fixes this.

2c94611d5f cros_ec: power: Add a tunnelled version of the tps65090 driver
Unfortunately on Pit the AP has no direct access to the tps65090 but must
talk through the EC (over SPI) to the EC's I2C bus.

When driver model supports PMICs this will be relatively easy. In the
meantime the best approach is to duplicate the driver. It will be refactored
once driver model support is expanded.
