The i2c probe functions here don't use the id information provided in
their second argument, so the single-parameter i2c probe function
("probe_new") can be used instead.
This avoids scanning the identifier tables during probes.

This device requires single register transactions, this will
definely cause problems with the new device ID parsing which uses
regmap_bulk_read but might also show up in the cache sync sometimes.
Add the missing flags to the regmap_config.

Now we can replace Codec to Component. Let's do it.
Note:

.ignore_pmdown_time = 0 -> .use_pmdown_time = 1
- -> .endianness = 1

codec driver and component driver has duplicated callback functions,
and codec side functions are just copied to component side when
register timing. This was quick-hack, but no longer needed.
This patch moves these functions from codec driver to component driver.

gcc warns about the possibilty of accessing a property read from
devicetree in cs35l32_i2c_probe() when it has not been initialized
because CONFIG_OF is disabled:
sound/soc/codecs/cs35l32.c: In function 'cs35l32_i2c_probe':
sound/soc/codecs/cs35l32.c:278:2: warning: 'val' may be used uninitialized in this function [-Wmaybe-uninitialized]
The code is actually correct because it checks the dev->of_node
variable first and we know this is NULL here when CONFIG_OF
is disabled, but Russell King noticed that it's broken when
we probe the device using DT, and the properties are absent.
The code already has some checking for incorrect values, and
I keep that checking unchanged here, but add an additional
check for an error returned by the property accessor functions
that now gets handled the same way as incorrect data in the
properties.

Use case range syntax makes the code shorter with better readability when
we have a large number of continuous switch cases.
Below are the summary of readable/volatile/precious registers.
The readable registers:
0x01 ~ 0x0D, 0x0F ~ 0x1C
The volatile registers:
0x01 ~ 0x05, 0x15 ~ 0x18
The precious registers:
0x15 ~ 0x18

Separate the functionality using sequences of register writes from the
functions that take register defaults. This change renames the arguments
in order to support the extension of reg_sequence to take an optional
delay to be applied after any given register in a sequence is written.
This avoids adding an int to all register defaults, which could
substantially increase memory usage for regmaps with large default tables.
This also updates all the clients of multi_reg_write/register_patch.

Since 39b2bbe3d715 (gpio: add flags argument to gpiod_get*() functions)
which appeared in v3.17-rc1, the gpiod_get* functions take an additional
parameter that allows to specify direction and initial value for
output. Simplify drivers accordingly.
Also there is an *_optional variant that serves well here. The sematics
is slightly changed here by using it as error checking is more strict
now: If GPIOLIB is not enabled an error is returned instead of just
ignoring the gpio. On one hand this is bad for devices that don't "have"
the respective gpio as the driver is failing now. On the other hand
there is no means to assert that this gpio is really not needed or if
only the driver to control it is not available. The latter is a real
reason to fail and so it's defensive to fail here, too.
