Yicong Yang 0f9d2fc588 i2c: hisi: Avoid redundant interrupts
[ Upstream commit cc9812a309 ]

After issuing all the messages we can disable the TX_EMPTY interrupts
to avoid handling redundant interrupts. For doing a sinlge bus
detection (i2cdetect -y -r 0) we can reduce ~97% interrupts (before
~12000 after ~400).
