ASoC: cs35l34: Improve two size determinations in cs35l34_i2c_probe()
Replace the specification of two data structures by pointer dereferences
as the parameter for the operator "sizeof" to make the corresponding size
determination a bit safer according to the Linux coding style convention.

This issue was detected by using the Coccinelle software.

a180ba45b1 ASoC: codecs: add const to snd_soc_codec_driver structures
Declare snd_soc_codec_driver structures as const as they are only passed
as an argument to the function snd_soc_register_codec. This argument is
of type const, so declare the structures with this property as const.
In file codecs/sn95031.c, snd_soc_codec_driver structure is also used in
a copy operation along with getting passed to snd_soc_register_codec.
So, it can be made const too.
Done using Coccinelle:

db3be255a1 ASoC: cs35l34: Remove unneeded gpiod NULL check
The gpiod API checks for NULL descriptors, so there is no need to
duplicate the check in the driver.

e8fa1a4929 ASoC: cs35l34: Constify hw_constraints
snd_pcm_hw_constraint_list(), *_ratnums() and *_ratdens() receive the
const pointers.  Constify the corresponding static objects for better
hardening.

914657c2be ASoC: cs35l34: Simplify the logic to set CS35L34_MCLK_CTL setting
The logic of "value = ~CS35L34_MCLK_DIV & CS35L34_MCLK_RATE_XXXXXX;" is
unnecessary complex. By setting CS35L34_MCLK_DIV | CS35L34_MCLK_RATE_MASK
as the mask for regmap_update_bits() call, what the code does is exactly
the same as setting value = CS35L34_MCLK_RATE_XXXXXX.

55060feefc ASoC: cs35l34: Remove CS35L34_CHIP_ID from cs35l34_readable_register
CS35L34_CHIP_ID is not a register address, it's the value read from
CS35L34_DEVID_AB/CD/E registers.
