This patch drops support for I2C devices with 10 bit addressing. When I2C
device with 10 bit address is defined in DT, I3C master registration fails.

Address space for I2C devices has been reduced and -&gt;i2c_funcs() hook has been
removed.

Because this patch series dropped support for 10 bit I2C devices, support is
also dropped in Cadence I3C master driver and Synopsys DesignWare I3C master
driver.

The controller was being disabled incorrectly. The correct way is to clear
the DEV_CTRL_ENABLE bit.

Fix this by clearing this bit.

In preparation to enabling -Wimplicit-fallthrough, mark switch
cases where we are expecting to fall through.

This patch fixes the following warning:

drivers/i3c/master/dw-i3c-master.c: In function ‘dw_i3c_master_bus_init’:
drivers/i3c/master/dw-i3c-master.c:603:6: warning: this statement may fall through [-Wimplicit-fallthrough=]
   if (ret)
      ^
drivers/i3c/master/dw-i3c-master.c:605:2: note: here
  case I3C_BUS_MODE_PURE:
  ^~~~

Warning level 3 was used: -Wimplicit-fallthrough=3

This patch is part of the ongoing efforts to enable
-Wimplicit-fallthrough.

In dw_i3c_master_irq_handler(), we already have gotten
&amp;master-&gt;xferqueue.lock, if we try to get the same lock again in
dw_i3c_master_dequeue_xfer(), deadlock happens.

We fix this issue by introduing dw_i3c_master_dequeue_xfer_locked()
which does all what dw_i3c_master_dequeue_xfer() does without trying
to lock &amp;master-&gt;xferqueue.lock.
