extcon: Remove optional print_name() function pointer of extcon_dev
This patch removes the optional print_name() function pointer included in 'struct extcon_dev' because the extcon must maintain the consistent name of extcon device on sysfs instead of inconsistent name. After merged patch[1], extcon can maintain the consistent name of extcon device without any hard-coded device name.
