aae6f016a7 mmc: cadence: use fdt32_t for DT property value to fix sparse warning
DTB is encoded in big endian.  When we retrieve property values,
we need to use fdt32_to_cpu (aka be32_to_cpu) for endian conversion.
This is a bit error-prone, but sparse is useful to detect endian
mismatch.

We need to use (fdt32_t *) instead of (u32 *) for a pointer of a
property value.  Otherwise sparse warns "cast to restricted __be32".

da409ccc4a dm: core: Replace of_offset with accessor (part 2)
At present devices use a simple integer offset to record the device tree
node associated with the device. In preparation for supporting a live
device tree, which uses a node pointer instead, refactor existing code to
access this field through an inline function.

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.

9d922450aa dm: Use dm.h header when driver mode is used
This header includes things that are needed to make driver build. Adjust
existing users to include that always, even if other dm/ includes are
present

0cacd6b755 mmc: sdhci-cadence: import updates from Linux 4.12
This driver is a counterpart of drivers/mmc/host/sdhci-cadence.c
from Linux.  Some updates for v4.12-rc1 can be imported to U-Boot.

 - Fix value of SDHCI_CDNS_HRS04_RDATA_SHIFT
 - Add polling for ACK bit to be sure that data are written to
   the PHY register
 - Retrieve PHY values from DT properties instead of fixed data

The following is the list of upstream commits:

 - Linux commit 4e03f628b464e0580abadf5161eaa38c61d20943
