[PATCH] LoongArch: defconfig: Enable generic I2C slave support

[Pengpeng Hou]

The DesignWare I2C slave object is now carried by the generic
`CONFIG_I2C_SLAVE` symbol:

  i2c-designware-core-$(CONFIG_I2C_SLAVE) += i2c-designware-slave.o

The LoongArch defconfigs still set the stale
`CONFIG_I2C_DESIGNWARE_SLAVE` symbol, which no longer carries that
provider object.  Switch the defconfigs to the current generic I2C slave
symbol so the intended slave support remains enabled.
