The compiler warns that [rf]wimsc may be used uninitialized in
this function - the warning is actually false since the uses are
in identical if()-clauses, but it can't hurt very much to read
out the values to be modified early anyway and rid the warning.

The NOMADIK_GPIO_PM config option is disabled by default, not user visible,
and never selected by any other option: the code is therefore unused. The
GPIO registers need not be saved and restored since their values are
preserved when vAPE (on DB8500) is powered down.

Setting pinmux alternative C for a GPIO pin is actually not
so easy since it ivolves setting value "1" in two registers,
and since the combined result will take effect for intermediate
values (01 or 10) this will cause glitches while you wrote one
register but have not yet written the other.

This patch implements a series of kludges including an optional
machine-specific callback to avoid glitches when changing pin
mux mode to alternative C.

When GPIOs wake up the system from sleep mode, the normal GPIO interrupt
handler does not hit and the normal interrupt status register does not
contain the status. Instead the secondary GPIO handler does, and the
interrupt status needs to be retrieved from the wakeup status saved by
the suspend/resume code.

The calculation of the best divider value for a requested clock rate
always returned a value that was slightly too large. It was also not
protected against possible divisions by zero.

Request for very low, but non zero rates would cause the ACLK divisor
field to overflow. Catch this situation by using the maximum value.

The internal function aclk_set_rate() calculates the correct divider
value, but doesn't write it back to the register. Add the write back.
