drivers/i2c: Cleanup Kconfig Move driver specific to dedicated file when relevant (i.e.: more than 1-2 options), use if/endif also. Signed-off-by: Tomasz Bursztyka <tomasz.bursztyka@linux.intel.com>

kconfig: Hide the DesignWare I2C driver on unsupported platforms When users are configuring nRF applications they are given the option to enable the DesignWare I2C driver. But they should not be given this option because nRF SoCs do not have DesignWare I2C HW. This commit hides the driver by default by introducing the config option HAS_I2C_DW.

drivers: i2c_dw: Remove hard-coded instance count assumption Introduce a Kconfig variable that the SoC can set to indicate the number of instances in Device Tree. This also fixes the accuracy of the Elkhart Lake instance count where the code was previously assuming up to 12 instances even though DT lists 15 nodes.
