i2c: amd-asf: Fix EOI register write to enable successive interrupts

Browse source 
The commit b1f8921dfb
("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.
