Subject: [PATCH 02/19] staging: iio: isl29028: remove enable flag from isl29028_enable_proximity()

isl29028_enable_proximity() has a boolean argument named enable. This
function is only called once and the enable flag is set to true in that
call. This patch removes the enable parameter from that function.
