[PATCH] power: max17042: divide by 0 Crash because r_sns init too late

[Philip Rakity <prakity@marvell.com>]

On MMP2 brownstone divide by 0 error since probe sets r_sns
after calling power_supply_register.

Move the code up a few lines.  r_sns comes from the platform
data.

PROP_CURRENT_AVG and PROP_CURRENT divide the result by r_sns.
