[PATCH v3 0/6] ASoC: Add NTP8918 and NTP8835 codecs support

[Igor Prusov <ivprusov@xxxxxxxxxxxxxxxxx>]

This series adds support for two NeoFidelity amplifiers. For both
amplifiers vendor provides software for equalizer and filters
configuration, which generates firmware files with registers values.
Since in both cases those files have same encoding, a common helper
module is added to get firmware via request_firmware() API and set
registers values.

Changes in V3:
- Added clocks to bindings and drivers
- removed unused includes
- ntp8835_reset_gpio() now only implements reset sequence and does not
  leave device in reset state
- make data const where possible
- Link to V2: https://lore.kernel.org/lkml/20240709221203.92167-5-ivprusov@xxxxxxxxxxxxxxxxx/

Changes in V2:
- Fix dt_binding_check errors
- Link to V1: https://lore.kernel.org/all/20240709172834.9785-1-ivprusov@xxxxxxxxxxxxxxxxx/
