At this point, the remaining places where we have a symbol that is
defined as CONFIG_... are in fairly odd locations. While as much dead
code has been removed as possible, some of these locations are simply
less obvious at first. In other cases, this code is used, but was
defined in such a way as to have been missed by earlier checks. Perform
a rename of all such remaining symbols to be CFG_... rather than
CONFIG_...

The uniphier i2c block can recognize some handshake errors.
But driver handles all error detections as no error if no timeout.
So this makes unrecoverable state.
This replaces the return values with the right ones to tell the i2c
framework the errors:
- EDEADLK for arbitration lost error
- ENODATA for no answer error

A late ack is currently being sent at the end of a transfer due to
incorrect logic in mchp_corei2c_empty_rx(). Currently the Assert Ack
bit is being written to the controller's control reg after the last
byte has been received, causing it to sent another byte with the ack.
Instead, the AA flag should be written to the control register when
the penultimate byte is read so it is sent out for the last byte.

Current function stm32_i2c_message_xfer is sending a STOP
whatever the result of the transaction is. This can cause issues
such as making the bus busy since the controller itself is already
sending automatically a STOP when a NACK is generated.

fix for this. [1]

The size of the dynamic stack allocation here is bounded by the if()
statement. However, just allocating the maximum size up-front and
doing malloc() if necessary avoids code duplication (the
i2c_setup_offset() until the invocation of ->xfer), and generates much
better (smaller) code:
bloat-o-meter drivers/i2c/i2c-uclass.o.{0,1}
add/remove: 0/0 grow/shrink: 0/1 up/down: 0/-144 (-144)
Function old new delta
dm_i2c_write 552 408 -144
Total: Before=3828, After=3684, chg -3.76%
It also makes static analysis of maximum stack usage (using the .su
files that are automatically generated during build) easier if there
are no lines saying "dynamic".
[This is not entirely equivalent to the existing code; this now uses
the stack for len <= 64 rather than len <= 63, but that seems like a
more natural limit.]

Tighten up symbol dependencies in a number of places. Ensure that a SPL
specific option has at least a direct dependency on SPL. In places
where it's clear that we depend on something more specific, use that
dependency instead. This means in a very small number of places we can
drop redundant dependencies.
