[PATCH] blackfin: portmux: define proper no-ops for peripheral_* for CONFIG_PINCTRL=y

[Marc Kleine-Budde]

When compiling blackfin code with CONFIG_PINCTRL=y, several functions
peripheral_* are no-oped by #define'ing them to nothing. This may lead to
unused variable warning in the code that's using the peripheral_* function.

This patch defines proper static inline no-op functions to fix these warnings.
