Add __regmap_init_i3c() and the corresponding regmap_init_i3c() macro to
allow creating a regmap for I3C devices without using the device-managed
version. This mirrors the pattern already established for other buses
such as I2C, SPI and so on, giving drivers more flexibility when
the regmap lifetime is not directly tied to the device.

Switch to use i3c_xfer instead of i3c_priv_xfer because framework will
update to support HDR mode. i3c_priv_xfer is now an alias of i3c_xfer.
Replace i3c_device_do_priv_xfers() with i3c_device_do_xfers(..., I3C_SDR)
to align with the new API.
Prepare for removal of i3c_priv_xfer and i3c_device_do_priv_xfers().

Use ARRAY_SIZE() instead of hard coded numbers to show the intention
and make code robust against potential changes.

'Regmap' should be spelled as 'regmap'. Update that.

The only usage of these is to pass their address to __regmap_init() or
__devm_regmap_init(), both which takes pointers to const struct
regmap_bus. Make them const to allow the compiler to put them in
read-only memory.

Add basic support for i3c bus.
This is a simple implementation that only give support
for SDR Read and Write commands.
