Subject: [PATCH v3 1/2] clk: imx25: print silicon revision during init

Print the imx25 silicon revision when the clocks are initialised.

Use the same mechanism as for imx27, i.e. call mx25_revision.
This function is unused at the moment.

changes in v3:
- rebase against today's linux-next

changes in v2:
- send the patch to the clk maintainers
