Add pending patches which add a PSE driver for the PSE setup found on
most of Realtek-based switches. An MCU with a Realtek-defined firmware
and protocol fronts one or more PSE chips (from Realtek or Broadcom) as
a management controller.
The driver provides both I2C/SMBus and UART communication, which varies
among our supported switches. There is no need for complicated userspace
handling anymore, the PSE setup is defined in the device tree and
interfaced in userspace via ethtool, netlink and netifd support.
Those patches have progressed far enough upstream, the bindings are
reviewed. Thus, we can keep this intermediate version downstream to open
it up earlier for usage. Only little changes are expected til the final
version lands.

The AddDepends/pse-pd helper appended kmod-pse-pd to DEPENDS without the
'+' prefix, making it a hard dependency rather than an auto-selecting one.
This breaks pulling any PSE controller driver (kmod-pse-pd692x0,
kmod-pse-si3474, kmod-pse-tps23881, kmod-pse-regulator, ...) in via a
device's DEVICE_PACKAGES: the kmod itself is auto-selected, but the
unsatisfied hard dep on kmod-pse-pd silently drops it from .config.
Prefix the kmod-pse-pd entry with '+' so it auto-selects, matching how
the other deps in the same file (kmod-i2c-core, etc.) are expressed. The
helper is the right place to fix this; every PSE controller driver routes
through it.

There are a number of pse chips already present in upstream Linux.
OpenWrt is starting to support a number of devices can contain various pse
chips. But having all the pse chip combinations defined at the target
level will result in bloat on images.
Present the current upstream Linux pse drivers as packages so that they
can be selectively included per board (rather than per target).
