Hello Linus,

Here are a few fixes for the i3c subsystem. We have the introduction of
the I3C_OR_I2C symbol which is not a fix per se but is affecting
multiple subsystems so it is included to ease synchronization. Apart
from this, Adrian is mostly fixing the mipi-i3c-hci driver around DMA
and wanted the fixes for 7.0. Finally, I took the opportunity to add two
fixes for the dw-i3c driver.

The following changes since commit 6de23f81a5e08be8fbf5e8d7e9febc72a5b5f27f:

  Linux 7.0-rc1 (2026-02-22 13:18:59 -0800)
