There are some missing reset reg_mode values for the 3840x2160@60 resolution.
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[].
