Migrate KSZ8863 driver to new I2C driver implementation

[bogdankolendovskyy]

Description

Migrate KSZ8863 driver to use i2c_master.h instead of legacy i2c.h. Examples updated accrodingly, and ioctl error

E (447) esp.emac: emac_esp_custom_ioctl(276): unknown io command: 4109

suppressed. It resulted from ETHERNET_EVENT_CONNECTED handler trying to use KSZ8863 custom ioctl command KSZ8863_ETH_CMD_G_PORT_NUM when host_eth_handle produced ETHERNET_EVENT_CONNECTED.

Forgot to reply here. I've tested that it builds and runs with v5.3. What other changes to idf_component.yml are needed in your opinion ?
