Those files do exist, and aren't pulled in by any other means I can see.
It was introduced by commit 6db92cc9d07db9f713da8554b4bcdfc8e54ad386, whose
changelog says:
Drivers can do the following in Kconfig to use these APIs "select
FSL_85XX_CACHE_SRAM if MPC85xx"

Now, the absence of such a kconfig option[1] is a problem, but I don't think
outright removal (labelled "trivial cleanup") is appropriate, unless nobody
fixes it after the problem is pointed out. And if it is removed, the files
should go with it.

[1] and of any drivers that select it, though this was added fairly
recently -- perhaps such a driver change is on its way?
