mb/google/dedede/var/storo: Modify eeprom setting for MIPI camera
Currently, it fails to dump the nvme data by test command.
It reports the following error:
cat: '/sys/bus/i2c/devices/i2c-PRP0001:01/eeprom': Connection timed out
So increase the value from 0x0400 to 0x2000 and double the address width from 0x08 to 0x10 to solve this problem.
BUG=b:177393430
TEST=1. cat /sys/bus/i2c/devices/i2c-PRP0001:01/eeprom > /tmp/ov8856_eeprom.bin
2. hexdump -C /tmp/ov8856_eeprom.bin > ov8856_eeprom_dump.log
3. cat ov8856_eeprom_dump.log
