David Lechner db63e45a7d iio: adc: ad_sigma_delta: use spi_optimize_message() 
Use spi_optimize_message() to improve the performance of buffered reads.

By setting up the SPI message and pre-optimizing it in the buffer
postenable callback, we can reduce overhead during each sample read.

A rough estimate shows that this reduced the CPU usage of the interrupt
handler thread from 22% to 16% using an EVAL-AD4112ARDZ board on a
DE10-Nano (measuring a single channel at the default 6.2 kHz sample
rate).

David Lechner 1519bedf88 iio: adc: ad_sigma_delta: refactor setting read address 
Refactor code to set the read address in a separate function.

This code is already duplicated twice and we will need to use it a third
time in a later commit.

David Lechner 86d8d6b8b9 iio: adc: ad_sigma_delta: audit included headers 
Drop linux/iio/sysfs.h since it is unused and replace linux/kernel.h
with more explicit headers. There are a couple of other headers added
weren't covered by kernel.h, like linux/gpio/consumer.h that are added
since the module makes use of those APIs as well.

David Lechner e916934b59 iio: adc: ad_sigma_delta: use BITS_TO_BYTES() macro 
Use the BITS_TO_BYTES() macro instead of dividing by 8 to convert bits
to bytes.

This makes it more obvious what unit conversion is taking place.

In one instance, we also avoid the temporary assignment to a variable
as it was confusing that reg_size was being used with two different
units (bits and bytes).

scan_type is factored out to reduce line wrapping.

David Lechner 11d58620df iio: adc: ad_sigma_delta: use u8 instead of uint8_t 
Replace uint8_t with u8 in the ad_sigma_delta driver.

Technically, uint8_t comes from the C standard library, while u8 is a
Linux kernel type. Since we don't use the C standard library in the
kernel, we should use the kernel types instead.

There is also one instance where int64_t is replaced with s64.

David Lechner b1c5f11dd1 iio: adc: ad7173: simplify clock enable/disable 
Use devm_clk_get_enabled() instead of devm_clk_get(),
clk_prepare_enable(), devm_add_action_or_reset() to simplify the
code as it effectively does the same thing.

We can also drop ext_clk from struct ad7173_state since it is not used
anywhere else.

The driver code is full of intXX_t and uintXX_t types which is
not the pattern we use in the IIO subsystem. Switch the driver
to use kernel internal types for that. No functional changes.
