When referring to array of phandles, using <> to separate the array
entries is better notation as it makes potential errors with phandle and
cell arguments easier to catch. Fix the outliers to be consistent with
the rest of the usage.

Why we need more than 2 pio lines for i2c node ,

pio lines? I am not sure I understand. If you are suggesting
eeprom_wp_pins to be moved to the eeprom node, It is probably
un-related to this series, but OK, i think it is probably a valid
change (unless Robert sees a reason why he did it the way he did).

correct, I am suggesting to move  eeprom_wp_pins_default to eeprom node.

i2c needs 2 lines which are defined in wkup_i2c0_pins_default, Adding 
eeprom_wp_pins_default will not be true representation of i2c node.

It will be good to have similar changes in main_i2c1 and main_i2c5  node 
for csi0_gpio_pins_default and csi1_gpio_pins_default.
