i3c: master: Add driver for AMD AXI I3C master controller
Add an I3C master driver and maintainers fragment for the AMD I3C bus
controller.
The driver currently supports the I3C bus operating in SDR mode,
with features including Dynamic Address Assignment, private data
transfers, and CCC transfers in both broadcast and direct modes. It
also supports operation in I2C mode.
The controller's data FIFOs are accessed big-endian; the driver performs
this conversion locally using ioread32be()/iowrite32be() with the
helpers, so it does not depend on any core FIFO-endianness helpers.
