The commit b1f8921dfbaa ("i2c: amd-asf: Clear remote IRR bit to get successive interrupt") introduced a method to enable successive interrupts but inadvertently omitted the necessary write to the EOI register, resulting in a failure to receive successive interrupts.

Fix this by adding the required write to the EOI register.
