[GIT PULL] at24: updates for v5.6

[Bartosz Golaszewski <brgl@bgdev.pl>]

From: Bartosz Golaszewski <bgolaszewski@baylibre.com>

Hi Wolfram,

I'm sorry for the late PR. I was (still am actually) OoO for family
reasons. I hope you can still pull this for the next merge window.

This time the release is pretty big for this driver. We have moved the
support for write-protect pin control into the core nvmem library so that
all nvmem users can use it automatically. All nvmem changes were acked by
Srinivas and have been in next for some time. The DT binding document for
at25 was updated and the patch was acked by Greg KH. The driver also now
supports regulator control and has suspend/resume callbacks.

Best regards,
Bartosz
