drivers: soc: ti: knav_qmss_queue: Mark knav_acc_firmwares as static

[ Upstream commit adf85ad ]

There is a sparse warning shown below:

drivers/soc/ti/knav_qmss_queue.c:70:12: warning: symbol
'knav_acc_firmwares' was not declared. Should it be static?

Since 'knav_acc_firmwares' is only called within knav_qmss_queue.c,
mark it as static to fix the warning.
