Sébastien Szymanski eefd93e7f8 power: pmic_pca9450: fix PCA9450A I2C address 
Quoting Ye Li from NXP:

    "We have confirmed with PMIC team, 0x35 is used only on early chips
    and not used any more. 0x25 is the final address."

Fix it by merging power_pca9450a_init and power_pca9450b_init into one
function power_pca9450_init.

U-Boot for the NXP i.MX8MP EVK board

Quick Start
===========
- Build the ARM Trusted firmware binary
- Get the firmware-imx package
- Build U-Boot
- Boot

Get and Build the ARM Trusted firmware
======================================
Note: $(srctree) is the U-Boot source directory
Get ATF from: https://source.codeaurora.org/external/imx/imx-atf
branch: imx_5.4.3_2.0.0
$ make PLAT=imx8mp bl31
$ sudo cp build/imx8mp/release/bl31.bin $(srctree)

Get the ddr firmware
====================
$ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-8.7.bin
$ chmod +x firmware-imx-8.7.bin
$ ./firmware-imx-8.7
$ sudo cp firmware-imx-8.7/firmware/ddr/synopsys/lpddr4_pmu_train_1d_dmem_201904.bin $(srctree)/lpddr4_pmu_train_1d_dmem.bin
$ sudo cp firmware-imx-8.7/firmware/ddr/synopsys/lpddr4_pmu_train_1d_imem_201904.bin $(srctree)/lpddr4_pmu_train_1d_imem.bin
$ sudo cp firmware-imx-8.7/firmware/ddr/synopsys/lpddr4_pmu_train_2d_dmem_201904.bin $(srctree)/lpddr4_pmu_train_2d_dmem.bin
$ sudo cp firmware-imx-8.7/firmware/ddr/synopsys/lpddr4_pmu_train_2d_imem_201904.bin $(srctree)/lpddr4_pmu_train_2d_imem.bin

Build U-Boot
============
$ export CROSS_COMPILE=aarch64-poky-linux-
$ make imx8mp_evk_defconfig
$ export ATF_LOAD_ADDR=0x960000
$ make flash.bin

Burn the flash.bin to the MicroSD card at offset 32KB
$sudo dd if=flash.bin of=/dev/sd[x] bs=1K seek=32; sync

Boot
====
Set Boot switch to SD boot
Use /dev/ttyUSB2 for U-Boot console
