Implement support for framebuffers that don't start on a page boundary. This happens on the new 14" and 16" Macbook Pro where we deliberately use a framebuffer that skips the first few lines to avoid "the notch". The offset of the first pixel is added to struct wsdisplay_fbinfo. The stride is added as well, mirroring the value returned by the WSDISPLAYIO_LINEBYTES ioctl, such that we can retire that one in the future. A compat ioctl is implemented to help the transition. The compat code will be removed after OpenBSD 7.3 has been released.

Add a pseudo-driver to "kexec" an OpenBSD/powerpc64 kernel. Heavily based on the octboot driver that we use for octeon. To be used in the bootloader kernel.

don't need to put config_activate_children inside cfattach, because NULL means the same ok kettenis

Extend struct todr_chip_handle with a todr_quality member. This allows us to assign a quality to RTC implementation and pick the "best" RTC if a system has multiple RTCs (or multiple interfaces to an RTC). This allows us to prefer a battery-backed I2C RTC over an RTC that is part of the SoC which is only running of the SoC is powered. It also allows us to work around issues with firmware RTC interfaces that may lie to us or even crash the system.

A bit of MSI support code; we need to distinguish between 32-bit and 64-bit MSIs on powerpc64.
