clk: pxa: fix pxa27x CCCR bit usage
Trivial fix to check the A bit of CCCR for memory frequency calculations, where the shift of the bit index was missing, triggering a wrong calculation of memory frequency. Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr> Signed-off-by: Michael Turquette <mturquette@linaro.org>
