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")
