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.

dm: core: Replace of_offset with accessor

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.

exynos: spi: Convert the timeout to debug()

Since the timeout is reported through normal channels, and is sometimes
expected (e.g. if the bus is being probed for a non-existent device),
don't display the message in the driver.

In general, drivers should not write to the console as this limits their
usefulness in error conditions.

These methods should be passed a slave device, not a bus. This matches the

so passing a bus is not that useful.

Exynos: SPI: Fix reading data from SPI flash

SPI recieve and transfer code in exynos_spi driver has a logical bug.
We read data in a variable which can hold an integer. Then we assign
this integer 32 bit value to another variable which has data type uchar.
Latter represents a unit of our recieve buffer. Everytime when we write
a value to our recieve buffer we step ahead by 4 units when actually we
wrote to one unit. This results in the loss of 3 bytes out of every 4
bytes recieved. This patch intends to fix this bug.
