Jian Zhang 53fa188f64 i2c: aspeed: Fix i2c bus hang in slave read 
commit 54f1840ddee9bbdc8dd89fbbfdfa632401244146 upstream.

When the `CONFIG_I2C_SLAVE` option is enabled and the device operates
as a slave, a situation arises where the master sends a START signal
without the accompanying STOP signal. This action results in a
persistent I2C bus timeout. The core issue stems from the fact that
the i2c controller remains in a slave read state without a timeout
mechanism. As a consequence, the bus perpetually experiences timeouts.

In this case, the i2c bus will be reset, but the slave_state reset is
missing.
