You passed the parameter in the wrong order, bus number must be first
and slave address second.

Maybe in some document you have, it is, but not for the Linux kernel,
which uses right-aligned 7-bit slave addresses. 0xa8 is obviously a
left-aligned 7-bit address. So the address you actually want to pass to
i2cdump is 0xA8 >> 1 == 0x54.
