[linux-yocto] [PATCH 12/17] i2c: designware: Make dw_readl() and dw_writel() static

[weifeng.voon at intel.com]

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

dw_readl() and dw_writel() are not used outside of i2c-designware-core and
they are not exported so make them static and remove their forward
declaration.
