When commit f9eb91350bb2 ("i2c: aspeed: added slave support for Aspeed
I2C driver") added slave mode support, the SLAVE_MATCH interrupt bit
(bit 7) was not added to INTR_ALL and so will never be set by the Aspeed
I2C controller.

I am working on slave mode in QEMU and noticed that the device would not
generate the SLAVE_ADDR_RX_MATCH interrupt. This patch fixes it, but I
do not have a spec sheet on the Aspeed, so I am not sure if this is the
intended behavior?
