The camera sensor still works in 3840x2160@60 resolution mode because of the register reset values. This is an issue when we change the modes dynamically. As an example, when we change the mode from 1920x1080@30 resolution to 3840x2160@60 resoultion then the mode values will be written to the registers from the array mode_3840x2160_regs[] which gives the wrong output which is incorrect resolution. So add the missing reset values to the mode_3840x2160_regs[].
