Just use longer nails in the clips into the mortar.

It's not really the depth of the hole which is the issue. The important thing is the 'width' of the hole. If the plug is not a fairly tight fit in the hole, it will not 'grip' when expanded (slightly) by the nail.
That really depends upon the mortar.
In my house, in a similar fashion to the situation with the plaster, the walls have one of two types of mortar - one type is like concrete, at least as hard as brick and all-but-impossible to get any sort of nail into. The other type is like sand, and the only effect that using a longer nail would have in that would be to make more of the 'sand' fall out
However, the OP might be lucky in having some sort of 'happy medium' mortar to deal with! However, as has been suggested, there are several other options available to him.
If the mortar is that soft then do it the old fashioned way of hammering in a piece of wood for the clip nails.

Yep, that's yet another option. That's how many of the skirtings (and other things) in my house are 'attached'.
A plug of timber, hammered into the joint, then allows the nail clip to be used.
EFLI beat you to that one
Yet another option .... although experiences vary a lot (and are often disappointing) some of the 'self-adhesive'cable clips do seem capable of sticking reasonably well to bricks.
When the result is 'disappointing' (clips fall off) a blob of Gripfill or similar often does the job.
In fact, sticking the cable directly to the wall is yet another option, although one has to be a little careful about what adhesive one used - I imagine that 'solvent-free' grab adhesives would be fairly safe with PVC cables I've done that in my time)

Digging out enough space for a timber plug and cutting one to size sounds like even more effort than drilling/plugging/screwing to the bricks was.
Very probably - although with the 'sand' variety of mortar, the 'digging out' only takes a few seconds.
and they always do work.
That's excellent. I didn't even know these existed!
If its quite a sizeable gap between plasterboard and brickwork then a few loops of all round band screwed and plugged to the wall is another solution

As I've mentioned, the important thing about using them is that the hole one drills has to be small enough that the plug is a fairly tight fit - the nail is only able to expand the plug slightly, so that, if the plug is loose in the hole, it may well not expand enough to grip.

I've done exactly that too.
