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.

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

Add OMAP SSI driver to the HSI subsystem.
The Synchronous Serial Interface (SSI) is a legacy version
of HSI. As in the case of HSI, it is mainly used to connect
Application engines (APE) with cellular modem engines (CMT)
in cellular handsets.
It provides a multichannel, full-duplex, multi-core communication
with no reference clock. The OMAP SSI block is capable of reaching
speeds of 110 Mbit/s.
