i3c/master: introduce the mipi-i3c-hci driver This adds basic support for hardware implementing the MIPI I3C HCI specification. This driver is currently limited by the capabilities of the I3C subsystem, meaning things like scheduled commands, auto-commands and NCM mode are not yet supported. This supports version 1.0 of the MIPI I3C HCI spec, as well as the imminent release of version 1.1. Support for draft version 2.0 of the spec is also largely included with the caveat that future adjustments to this code are likely as the spec is still a work in progress. This is also lightly tested as actual hardware is still very scarce, even for HCI v1.0. Hence the EXPERIMENTAL tag. Further contributions to this driver are expected once vendor implementations and new I3C devices become available.

i3c: master: svc: Add Silvaco I3C master driver Add support for Silvaco I3C dual-role IP. The master role is supported in SDR mode only. I2C transfers have not been tested but are shared because they are very close to the I3C transfers in terms of register configuration. The IBI processing follows this logic: - When a slave advertizes an interrupt (SDA pulled low) an interrupt gets generated by the master. This time is unbounded and may be deferred. - The IRQ handler itself does not process anything: it only queues a work that will be run in non-atomic context. This is needed because short wait periods must be experienced. - The IBI job is divided in two parts: the first one is "critical" in the sense that it may not support getting interrupted. If this happens, after this first section the driver checks the master error register and depending on its content either flushes everything and errors out, or ends the processing (this second section may be interrupted). - If the critical section got interrupted, the slave will automatically respin it's IBI request when it will be allowed to.

i3c/master/mipi-i3c-hci: Specify HAS_IOMEM dependency The MIPI i3c HCI driver makes use of IOMEM functions like devm_platform_ioremap_resource(), which are only available if CONFIG_HAS_IOMEM is defined. This causes the driver to be enabled under make ARCH=um allyesconfig, even though it won't build. By adding a dependency on HAS_IOMEM, the driver will not be enabled on architectures which don't support it.
