Subject: [PATCH v9 2/4] media: i2c: imx334: add missing reset values for mode 3840x2160_regs[]

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[].
