HSI: omap-ssi: move omap_ssi_port_update_fclk
After the clk change support, the ssi omap ssi core driver
now calls into the port driver to change fclk. This function
was previously inside of an #ifdef, because it was only used
when CONFIG_PM is enabled. Now it also gets used without
power management support:
drivers/hsi/built-in.o: In function `ssi_clk_event':
omap_ssi_port.c:(.text+0x1bf8): undefined reference to `omap_ssi_port_update_fclk'
This moves the function outside of the CONFIG_PM guard.
