The pattern used in this device does not quite fit in the
iio_device_claim_direct_mode() typical usage. In this case, we want to
know if we are in buffered mode or not to know if the device is powered
(buffer mode) or not. And depending on that max30102_get_temp() will
power on the device if needed. Hence, in order to keep the same
functionality, we try to:
1. Claim Buffered mode;
2: If 1) succeeds call max30102_get_temp() without powering on the
device;
3: Release Buffered mode;
4: If 1) fails, Claim Direct mode;
5: If 4) succeeds call max30102_get_temp() with powering on the device;
6: Release Direct mode;
7: If 4) fails, goto to 1) and try again.
This dance between buffered and direct mode is not particularly pretty
(as well as the loop introduced by the goto statement) but it does allow
us to get rid of the mlock usage while keeping the same behavior.

The pattern used in this device does not quite fit in the

iio_buffer_enabled() was being used not to prevent the raw
access but to allow it. Hence, let's make use of the new
iio_device_claim_buffer_mode() API to make sure we stay in
buffered mode during the complete read.
Note that we are shadowing the error code returned by
iio_device_claim_buffer_mode() so that we keep the original one
(-EAGAIN). The reason is that some userspace stack might already be
relying on this particular code so that we are not taking chances and
leave it alone.

In order to drop the internal lock usage we needed two different things:
1) The first place where 'mlock' was being used was a typical case where
iio_device_claim_direct_mode() fits perfectly.
2) In the second case, it was being used to prevent concurrent accesses
to the device and shared data but nothing was being enforced with
regards to buffering (i.e, there was nothing preventing from changing
the conversion mode while buffering). Hence, in this case, a new lock
was introduced in the state structure.
Note that the goal is not to introduce any functional change and that is
the reason why a new lock was introduced to guarantee 2).

SPI devices use the spi_device_id for module autoloading even on
systems using device tree, after commit 5fa6863ba6 ("spi: Check
we have a spi_device_id for each DT compatible"), kernel warns as
follows since the spi_device_id is missing:
SPI driver ad9467 has no spi_device_id for adi,ad9265
SPI driver ad9467 has no spi_device_id for adi,ad9434
Add spi_device_id entries to silence the warnings, and ensure driver
module autoloading works.
