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.

i2c: i2c-cdns: Implement workaround for hold quirk of the rev 1.0

Revision 1.0 of this IP has a quirk where if during a long read transfer
the transfer_size register will go to 0, the master will send a NACK to
the slave prematurely.
The way to work around this is to reprogram the transfer_size register
mid-transfer when the only the receive fifo is known full, i.e. the I2C
bus is known non-active.
The workaround is based on the implementation in the linux-kernel.

i2c: i2c-cdns: Detect unsupported sequences for rev 1.0

Revision 1.0 of this IP has a couple of issues, such as not supporting
repeated start conditions for read transfers.

So scan through the list of i2c messages for these conditions
and report an error if they are attempted.

This has been fixed for revision 1.4 of the IP, so only report the error
when the IP can really not do it.
