Use kunit_device_register() to create a real struct device for the
regmap instead of leaving it at NULL.
The main reason for this is that it allows context data to be passed
into the readable_reg/writable_reg/volatile_reg functions by attaching
it to the struct device with dev_set_drvdata().
The gen_regmap() and gen_raw_regmap() functions are updated to take a
struct kunit * argument.
A new struct regmap_test_priv has been created to hold the struct device
created by kunit_device_register(). This allows the struct to be
extended in the future to hold more private data for the test suite.

When compiling with gcc version 14.0.0 20231220 (experimental)
and W=1, I've noticed a bunch of four similar warnings like:
drivers/base/regmap/regmap-ram.c: In function '__regmap_init_ram':
drivers/base/regmap/regmap-ram.c:68:37: warning: 'kcalloc' sizes specified with
'sizeof' in the earlier argument and not in the later argument [-Wcalloc-transposed-args]
68 | data->read = kcalloc(sizeof(bool), config->max_register + 1,
| ^~~~
Since 'n' and 'size' arguments of 'kcalloc()' are multiplied to
calculate the final size, their actual order doesn't affect the
result and so this is not a bug. But it's still worth to fix it.

Support noinc semantics in RAM backed regmaps, for testing purposes. Add
a new callback that selects registers which should have noinc behavior.
Bulk writes to a noinc register will cause the last value in the buffer
to be assigned to the register, while bulk reads will copy the same
value repeatedly into the buffer.
This patch only adds support to regmap-raw-ram, since regmap-ram does
not support bulk operations.

Provide a simple, 16 bit only, RAM backed regmap which supports raw I/O for
use in testing.
