pinctrl: Introduce struct pinfunction and PINCTRL_PINFUNCTION() macro
[ Upstream commit 443a0a0f0cf4f432c7af6654b7f2f920d411d379 ] There are many pin control drivers define their own data type for pin function representation which is the same or embed the same data as newly introduced one. Provide the data type and convenient macro for all pin control drivers.
