iio: at91: fix adc_clk overflow
The adc_clk variable is currently defined using a 32-bits unsigned integer,
which will overflow under some very valid range of operations.
Such overflow will occur if, for example, the parent clock is set to a
20MHz frequency and the ADC startup time is larger than 215ns.
To fix this, introduce an intermediate variable holding the clock rate
in kHz.
