media: ti-vpe: cal: fix stop state timeout
The stop-state timeout needs to be over 100us as per CSI spec. With the CAL fclk of 266 MHZ on DRA76, with the current value the driver uses, the timeout is 24us. Too small timeout will cause failure to enable the streaming. Also, the fclk can be different on other SoCs, as is the case with AM65x where the fclk is 250 MHz. This patch fixes the timeout by calculating it correctly based on the fclk rate.
