PCI/pwrctrl: Rename pwrctl files to pwrctrl To slightly reduce confusion between "pwrctl" (the power controller and power sequencing framework) and "bwctrl" (the bandwidth controller), rename "pwrctl" to "pwrctrl" so they use the same "ctrl" suffix. Rename drivers/pci/pwrctl/ to drivers/pci/pwrctrl/, including the related MAINTAINERS, include file (include/linux/pci-pwrctl.h), Makefile, and Kconfig changes. This is the minimal rename of files only. A subsequent commit will rename functions and data structures.

PCI/pwrctrl: Rename pwrctrl Kconfig symbols and slot module Commits b88cbaaa6fa1 ("PCI/pwrctrl: Rename pwrctl files to pwrctrl") and 3f925cd62874 ("PCI/pwrctrl: Rename pwrctrl functions and structures") renamed the "pwrctl" framework to "pwrctrl" for consistency reasons. Rename also the Kconfig symbols so that they reflect the new name while adding entries for the deprecated ones. The old symbols can be removed once everything that depends on them has been updated. Note that no deprecated symbol is added for the new slot driver to avoid having to add a user visible option. Rename the new slot module to reflect the framework name and match the other pwrctrl modules.

PCI/pwrctrl: Add pwrctrl driver for PCI slots This driver is used to control the power state of the devices attached to the PCI slots. Currently, it controls the voltage rails of the PCI slots defined in the devicetree node of the root port. The voltage rails for PCI slots are documented in the DT-schema: https://github.com/devicetree-org/dt-schema/blob/v2024.11/dtschema/schemas/pci/pci-bus-common.yaml#L153 Since this driver has to work with different kind of slots (PCIe x1/x4/x8/x16, Mini PCIe, PCI, etc.), the driver is thus using the of_regulator_bulk_get_all() API to obtain the voltage regulators defined in the DT node, instead of hardcoding them. As such, the DT node of the root port should define the relevant supply properties corresponding to the voltage rails of the PCI slot.
