This fixes a lockup that occured when we brought up a core (after reboot) that had previously been placed into RESET by siba_bwn(4).

These changes add support for: - Writing raw voltage register values to PHY-specific LDO regulator registers (required by LP-PHY). - Enabling/disabling PHY-specific LDOs (required by LP-PHY) - Writing to arbitrary PMU chipctrl registers (required for common PHY PLL reset support). - Requesting chipset/PLL-specific spurious signal avoidance modes. - Querying clock frequency and latency. Additionally, rather than updating legacy PWRCTL support to conform to the new PMU interface: - PWRCTL API is now provided by a bhnd_pwrctl_if.m interface. - Since PWRCTL is only found in older SSB-based chipsets, translation from bhnd(4) bus APIs to corresponding PWRCTL operations is now handled entirely within the siba(4) driver. - The PWRCTL-specific host bridge clock gating APIs in bhnd_bus_if.m have been lifted out into a standalone bhnd_pwrctl_hostb_if.m interface.

On BHND PCI devices, backplane interrupt vectors are now routed to the PCI/PCIe host bridge core when bus_setup_intr() is called, where they are dispatched by the PCI core via a host interrupt (e.g. INTx/MSI). The bhndb(4) bridge driver tracks registered interrupt handlers for the bridged bhnd(4) devices and manages backplane interrupt routing, while delegating actual bus interrupt setup/teardown to the parent bus on behalf of the bridged cores.

This allows us to use the EROM parser API in cases where the standard bus space I/O APIs are unsuitable. In particular, this will allow us to parse the device enumeration table directly from bhndb(4) drivers, prior to full attach and configuration of the bridge.

Dump the EROM tables to the coneole on mips/broadcom devices if bootverbose is enabled; this functionality is primarily useful when debugging SoC EROM parsing and device matching issues during early boot.
