'-1' is absolutely meaningless value.
This patch changed from meaningless value to error number.

Use the generic pmic_bus helpers for the axp152 / axp209 drivers,
rather then having them define their own register read / write
functions.

Stop prefixing the axp functions for setting voltages, etc. with the
model number, there ever is only one pmic driver built into u-boot,
this allows simplifying the callers.

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.

Add support for the x-powers axp152 pmic which is found on most A10s boards
and enable it for the r7-tv-dongle board.
