[linux-yocto] [PATCH 11/17] i2c: designware: Remove unused functions

[weifeng.voon at intel.com]

From: Jarkko Nikula <jarkko.nikula at linux.intel.com>

i2c_dw_is_enabled() became unused by the commit be58eda775c8
("i2c: designware-pci: Cleanup driver power management") and
i2c_dw_enable() by the commit 3a48d1c08fe0 ("i2c: prevent spurious
interrupt on Designware controllers").
