Some of t1042 boards fails DDR init with an Automatic calibration error
every now and then. Investigations revealed that true Warm boots
never failed. Warm boots has some extra steps performed, one being
to start DDRC in Self Refresh and then clearing SR right after.
Applying this SR method unconditionally made all our boards
stable again, regardless of Cold/Warm boot.

Merge tag 'u-boot-atmel-fixes-2020.01-a' of https://gitlab.denx.de/u-boot/custodians/u-boot-atmel
- First set of u-boot-atmel fixes for 2020.01 cycle:
This set includes a small fix for gpio bank names, one for removing
unused headers (also touches some other boards), and a fix for the QSPI
env read on one of the boards.
This fixes an issue that would cause I2C writes to timeout when the
number of bytes is a multiple of the FIFO depth (i.e. 16 bytes).
Within the transfer loop, after writing the data register with a new
byte to transfer, if the transfer size equals the FIFO depth, the loop
pauses until the INTERRUPT_COMP bit asserts to indicate data has been
sent. This same check is performed after the loop as well to ensure data
has been transferred prior to returning.
In the case where the amount of data to be written is a multiple of the
FIFO depth, the transfer loop would wait for the INTERRUPT_COMP bit to
assert after writing the final byte, and then wait for this bit to
assert once more. However, since the transfer has finished at this
point, no new data has been written to the data register, and hence
INTERRUPT_COMP will never assert.
Fix this by only waiting for INTERRUPT_COMP in the transfer loop if
there's still data to be written.
