drm/msm/adreno: a5xx_power: Don't apply A540 lm_setup to other GPUs

BugLink: https://bugs.launchpad.net/bugs/1923874
[ Upstream commit 4a9d36b0610aa7034340e976652e5b43320dd7c5 ]

While passing the A530-specific lm_setup func to A530 and A540
to !A530 was fine back when only these two were supported, it
certainly is not a good idea to send A540 specifics to smaller
GPUs like A508 and friends.
