Subject: [PATCHv2] ARM: at91/dt: sam9261: Fix PLL output ranges and other clocks divisors

Argument 3 (OUT) and 4 (ICPLL) of the atmel,pll-clk-output-ranges were missing.
Also, the at91sam9261 doesn't really have a by 3 divisor.

Signed-off-by: Alexandre Belloni <alexandre.belloni@...e-electrons.com>

Changed in v2:
After getting feedback from the atmel HW engineers, it appears that PLLB is not
the same as PLLA despite what the datasheet seems to imply. The patch is updated
to reflect that.
