clk: bcm2835: add missing osc and per clocks
Add AVE0, DFT, GP0, GP1, GP2, SLIM, SMI, TEC, DPI, CAM0, CAM1, DSI0E, and DSI1E. PULSE is not added because it has an extra divider. Signed-off-by: Martin Sperl <kernel@martin.sperl.org> Signed-off-by: Eric Anholt <eric@anholt.net> Reviewed-by: Eric Anholt <eric@anholt.net>
