Subject: [PATCH] ARM: rpi: move clks into board specific rpi-common
We don't know if the firmware running on the raspberry pi is the same firmware
which is running on all bcm283x devices.
Therefore move the console clock initialization into the rpi-common.c board file.
A future commit will use this function to retrieve the miniuart clock from the
raspberry pi firmware.
No functional changes.
