[PATCH v4 0/3] Remove the pins-are-numbered DT property

[Bernhard Rosenkränzer]

During the review of my MT8365 support patchset
(https://lore.kernel.org/linux-mediatek/20221117210356.3178578-1-bero@baylibre.com/),
the issue of the "pins-are-numbered" DeviceTree property has come up.

This property is unique to Mediatek MT65xx and STM32 pinctrls, and
doesn't seem to serve any purpose (both the Mediatek and STM32 drivers
simply refuse to deal with a device unless pins-are-numbered is set to
true).

There is no other use of this property in the kernel or in other projects
using DeviceTrees (checked u-boot and FreeBSD -- in both of those, the
flag is present in Mediatek and STM devicetrees, but not used anywhere).

There is also no known use in userspace (in fact, a userland application
relying on the property would be broken because it would get true on
any Mediatek or STM chipset and false on all others, even though other
chipsets use numbered pins).

This patchset removes all uses of pins-are-numbered and marks the
property as deprecated.

v4:
  - The generic pinctrl related patches are now in the pinctrl tree
    for v6.2 - remove them and repost the remaining bits of the patch
    set. No other changes.

v3:
  - No functional changes; add recent Reviewed-Bys and Acked-Bys,
    add linux-gpio to Cc

v2:
  - Deprecate the property instead of removing it completely from
    schemas
  - squash some related commits
