i2c: pxa: migrate to new i2c_slave APIs
The i2c subsystem was enhanced circa 2015 to support operating as an i2c-slave device. Prior to that, the i2c-pxa driver supported an i2c-slave but had its own APIs. There are no existing in-kernel drivers or platforms that utilize the i2c-pxa APIs. Migrate the i2c-pxa driver to the general i2c-slave APIs so that existing drivers, such as the i2c-slave-eeprom, can be used. This has been tested with a Marvell EspressoBin, using i2c-pxa and i2c-slave-eeprom, acting as a slave, and a RaspeberryPi 3, using the at24 driver, acting as a master.
