soc: ti: fix wkup_m3_rproc_boot_thread return type

From: Arnd Bergmann <[email protected]>

The wkup_m3_rproc_boot_thread() function uses a nonstandard prototype, which broke after Eric's recent cleanup:

drivers/soc/ti/wkup_m3_ipc.c: In function 'wkup_m3_rproc_boot_thread':
drivers/soc/ti/wkup_m3_ipc.c:429:16: error: 'return' with a value, in function returning void [-Werror=return-type]
429 | return 0;
| ^
drivers/soc/ti/wkup_m3_ipc.c:416:13: note: declared here
416 | static void wkup_m3_rproc_boot_thread(struct wkup_m3_ipc *m3_ipc)

     |             ^~~~~~~~~~~~~~~~~~~~~~~~~

Change it to the normal prototype as it should have been from the start.

Fixes 111e70490d2a ("exit/kthread: Have kernel threads return instead of calling do_exit")

Fixes cdd5de500b2c ("soc: ti: Add wkup_m3_ipc driver")
