The driver now uses some pinctrl functions, but fails
to build if PINCTRL is disabled because the respective
header files are only included indirectly:
drivers/hsi/controllers/omap_ssi_core.c: In function 'ssi_clk_event':
drivers/hsi/controllers/omap_ssi_core.c:317:4: error: implicit declaration of function 'pinctrl_pm_select_idle_state' [-Werror=implicit-function-declaration]
drivers/hsi/controllers/omap_ssi_core.c:339:4: error: implicit declaration of function 'pinctrl_pm_select_default_state' [-Werror=implicit-function-declaration]
drivers/hsi/controllers/omap_ssi_port.c: In function 'ssi_flush':
drivers/hsi/controllers/omap_ssi_port.c:520:2: error: implicit declaration of function 'pinctrl_pm_select_idle_state' [-Werror=implicit-function-declaration]
This includes the headers from the files that call the functions,
which works even if pinctrl is turned off.

This adds support for frequency changes of the SSI
functional clock, which may occur due to DVFS.

Merge omap_ssi and omap_ssi_port into one module. This
fixes problems with module cycle dependencies introduced
by future patches.
