[media] gspca - ov534/ov534_9: Fix sccd_read/write errors
The ov534 bridge is too slow to handle the sensor accesses requested by fast hosts giving 'sccb_reg_write failed'. A small delay fixes the problem. Signed-off-by: Jean-François Moine <moinejf@free.fr> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
