This patch adds mode pin support to the sh7785lcr board.

The harware allows the user to control the mode pins using
dip switches S1 and S2, but from the software the pins are
fixed to the factory default since we have no way to reading
out this configuration from software.

This updates the SH7785 CPU code as well as the SH7785LCR board support
code for making use of the newly refactored clock framework. Support for
the legacy CPG clocks is dropped at this point, with the extal frequency
fed in from the board code.

Waiting for a free bus now accepts the timeout value in jiffies and does
proper checking using time_before.

Improve the sh7785lcr power off implementation to
never return. It takes some time before the board
is actually powered off, just hang after asking
the harware to power down.

This removes the serial port garbage printout.

This flattens out the board directories in to individual mach groups,
we will use this for getting rid of unneeded directories, simplifying
the build system, and becoming more coherent with the refactored
arch/sh/include topology.
