[PATCH 6.1.y 1/2] soc: qcom: apr: make remove callback of apr driver void returned

[Sasha Levin <sashal@kernel.org>]

From: Dawei Li <set_pte_at@outlook.com>

[ Upstream commit 33ae3d0955943ac5bacfcb6911cf7cb74822bf8c ]

Since commit fc7a6209d571 ("bus: Make remove callback return void")
forces bus_type::remove be void-returned, it doesn't make much sense
for any bus based driver implementing remove callbalk to return
non-void to its caller.

As such, change the remove function for apr bus based drivers to
return void.
