Subject: [PATCH] i2c: imx-lpi2c: select CONFIG_I2C_SLAVE

From: Arnd Bergmann <arnd@...db.de>

The addition of target mode causes a build failure when CONFIG_I2C_SLAVE
is turned off:

drivers/i2c/busses/i2c-imx-lpi2c.c:1273:10: error: 'const struct i2c_algorithm' has no member named 'reg_target'
 1273 |         .reg_target     = lpi2c_imx_register_target,
      |          ^~~~~~~~~~
drivers/i2c/busses/i2c-imx-lpi2c.c:1274:10: error: 'const struct i2c_algorithm' has no member named 'unreg_target'
 1274 |         .unreg_target   = lpi2c_imx_unregister_target,
      |          ^~~~~~~~~~~~

Select the Kconfig symbol like we do for other similar drivers.
