The driver reporting IEEE80211_TX_STAT_ACK is not being handled
correctly. The driver should only report on TSR_TMO flag is not
set indicating no transmission errors and when not IEEE80211_TX_CTL_NO_ACK
is being requested.

It appears that the drivers does not go into power save correctly the
NULL data packets are not being transmitted because it not enabled
in mac80211.
The driver needs to capture ieee80211_is_nullfunc headers and
copy the duration_id to it's own duration data header.

It appears that the driver still transmits in CTS protect mode even
though it is not enabled in mac80211.
That is both packet types PK_TYPE_11GA and PK_TYPE_11GB both use CTS protect.
The only difference between them GA does not use B rates.
Find if only B rate in GB or GA in protect mode otherwise transmit packets
as PK_TYPE_11A.

Currently calls to wfx_alloc_hif are not checking for a null return
when a memory allocation fails and this leads to null pointer
dereferencing issues. Fix this by adding null pointer checks and
returning passing down -ENOMEM errors where necessary. The error
checking in the current driver is a bit sparse, so this may need
some extra attention later if required.

This adds support for the BMA254 variant of this
accelerometer. The only difference for the simple IIO
driver is that values are 12 bit and the temperature
offset differs by 1 degree.
Whilst wildcards in naming are normally frowned upon:
The cases where I have labeled variables "25x" is where the
models are identical, so as to make things easier for people
that want to add support for BMA253 and BMA255.

The dmaengine buffer has some length alignment requirements that can differ
from platform to platform. If the length alignment requirements are not met
unexpected behavior like dropping of samples can occur.
Currently these requirements are not reported and applications need to know
the requirements of the platform by some out-of-band means.
Add a new buffer attribute that reports the length alignment requirements
called `length_align_bytes`. The reported length alignment is in bytes that
means the buffer length alignment in sample sets depends on the number of
enabled channels and the bytes per channel. Applications using this
attribute to determine the buffer size requirements need to consider this.

Since the orginal scope of the driver was to only support
the pH product from Atlas it has evolved to other sensors.
Rename the file, driver name, and regmap to atlas-sensor which
reflects this, although keep CONFIG_ATLAS_PH_SENSOR to not cause
regressions with current configurations.
