Merge series "mfd/rtc/regulator: Drop board file support for Samsung PMIC" from Krzysztof Kozlowski <krzysztof.kozlowski@canonical.com>:

Hi,

The Samsung PMIC drivers since long time are used only on devicetree
platforms (Samsung Exynos) and there are no users with board files.

Drop the support for board files entirely and depend on OF for matching.

This makes the code smaller and simpler.

Dependencies
============
The MFD pieces are rebased on my previous sec-core dirver changes:
mfd: sec: Simplify getting of_device_id match data
https://lore.kernel.org/linux-samsung-soc/20210420113929.278082-1-krzysztof.kozlowski@canonical.com/T/#t

Applying - can be independent
=============================
The last RTC and regulator patches can be picked up independently via
regulator and rtc trees.  There are no board files currently, so the
code in these drivers is basically dead code and feature-bisection is
preserved.

Best regards,
Krzysztof
