For today the reattach function only update the device address on the
controller.

Update the location to the first available too, will optimize the
enumeration process avoiding additional checks to keep the available
positions on address table consecutive.

This patch adds support for THD_DEL (Data Hold Delay) to Cadence
I3C master constoller driver.

As per MIPI I3C Specification 1.0, Table 75 (page 142) defines
non-zero minimal tHD_PP timing on master output (Fig 65). This
setting allows to meet this timing on master's soc outputs,
regardless of PCB balancing.

I need to store address and lvr value for I2C devices without static definition
in DT. This allows secondary master to transmit DEFSLVS command properly.

Main changes between v4 and v5:
- Change in defslvs to use addr and lvr from i2c_dev_desc structure
- Change in CDNS and DW drivers to use addr and lvr from i2c_dev_desc structure

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 ->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.
