9b643e312d treewide: replace with error() with pr_err()
U-Boot widely uses error() as a bit noisier variant of printf().

This macro causes name conflict with the following line in
include/linux/compiler-gcc.h:

  # define __compiletime_error(message) __attribute__((error(message)))

This prevents us from using __compiletime_error(), and makes it
difficult to fully sync BUILD_BUG macros with Linux.  (Notice
Linux's BUILD_BUG_ON_MSG is implemented by using compiletime_assert().)

Let's convert error() into now treewide-available pr_err().

Done with the help of Coccinelle, excluing tools/ directory.

The semantic patch I used is as follows:

// <smpl>
@@@@
-error
+pr_err
 (...)
// </smpl>

819c626bb0 mmc: sti_sdhci: Rework sti_mmc_core_config()
Use struct udevice* as input parameter. Previous
parameters are retrieved through plat and priv data.

This to prepare to use the reset framework.

a821c4af79 dm: Rename dev_addr..() functions
These support the flat device tree. We want to use the dev_read_..()
prefix for functions that support both flat tree and live tree. So rename
the existing functions to avoid confusion.

In the end we will have:

   1. dev_read_addr...()    - works on devices, supports flat/live tree
   2. devfdt_get_addr...()  - current functions, flat tree only
   3. of_get_address() etc. - new functions, live tree only

All drivers will be written to use 1. That function will in turn call
either 2 or 3 depending on whether the flat or live tree is in use.

Note this involves changing some dead code - the imx_lpi2c.c file.

eee20f8132 STiH410: Add STi SDHCI driver
Add SDHCI host controller found on STMicroelectronics SoCs

On some ST SoCs, i.e. STiH407/STiH410, the MMC devices can live
inside a dedicated flashSS sub-system that provides an extend subset
of registers that can be used to configure the Arasan MMC/SD Host
Controller.

This means, that the SDHCI Arasan Controller can be configured to be
eMMC4.5 or 4.3 spec compliant.

W/o these settings the SDHCI will configure and use the MMC/SD
controller with limited features e.g. PIO mode, no DMA, no HS etc.
