Subject: [PATCH 1/3] HSI: omap-ssi: add COMMON_CLK dependency

Enabling the omap ssi driver without COMMON_CLK results in a build failure:

drivers/hsi/controllers/omap_ssi_core.c: In function 'ssi_clk_event':
drivers/hsi/controllers/omap_ssi_core.c:304:7: error: 'PRE_RATE_CHANGE' undeclared (first use in this function)

This adds a Kconfig dependency to avoid the invalid configuration.

Signed-off-by: Arnd Bergmann <arnd@...db.de>
Fixes: 4bcf7414528a ("HSI: omap-ssi: add clk change support")

 	  SSI is a legacy version of HSI. It is usually used to connect
 	  an application engine with a cellular modem.
