media: imx335: Set reserved register to default value
0x3a00 is a reserved register as per the datasheet. The driver
currently sets to it 0x01 while the datasheet claims 0x00 to be
the default value.
On one of the setup based on i.MX8MP platform with IMX335, this register
write broke the CSI-2 configuration. Setting 0x3a00 to its default
value (i.e. 0x00) fixed the issue. It is not clear from the datasheet
what this register write is responsible for but setting it to its default
value seems the right thing to do, provided it has been found
responsible to break CSI-2 configuration on one of the platform.
