Never use sizeof(type), always use destination var size! Anyway, there's more.

I don't think we need to perform this memcpy: we'll never see an instance of
both mt8186 and mt8188 drivers on the same machine, so you can safely just use
sof_mt8186_ops for mt8188...

...which obviously means that this becomes

	sof_mt8186_ops.drv = mt8188_dai;

and....

This does have the issue that it then means the ops struct isn't const
which isn't ideal.  It's also not the end of the world though so I don't
have super strong feelings.

We do the same for Intel devices, we have a common structure which is
copied and only the members that differ in specific SOCs are updated.
You're right that it's not constant, but it avoids copy-paste of a
rather large structure just to change a couple of lines.

OK, I will use sizeof(sof_mt8188_ops) instead.

Currently, I prefer to follow the same implementation as Intel devices.
It's easier to see a different ops exists for mt8188 in
sof_of_mt8188_desc and it really avoids copy-paste of a large
structure.


Additionally, I found a typo in the next line.

sof_mt8186_ops.num_drv = ARRAY_SIZE(mt8188_dai);
	^
This should be sof_mt8188_ops. I will correct it in V2.

Thanks,
Trevor
