[PATCH] remoteproc: ti_k3: fix -Wcast-function-type warning

[Arnd Bergmann]

From: Arnd Bergmann <a...@arndb.de>

The function cast causes a warning with "make W=1"

drivers/remoteproc/ti_k3_r5_remoteproc.c: In function 'k3_r5_probe':
drivers/remoteproc/ti_k3_r5_remoteproc.c:1368:12: warning: cast between 
incompatible function types from 'int (*)(struct platform_device *)' to 'void 
(*)(void *)' [-Wcast-function-type]

Rewrite the code to avoid the cast, and fix the incorrect return
type of the callback.

Fixes: 6dedbd1d5443 ("remoteproc: k3-r5: Add a remoteproc driver for R5F 
subsystem")
