clk: mvebu: armada-370: maintain clock init order

Init order of CLK_OF_DECLARE'd drivers depends on compile order.
Unfortunately, clk_of_init does not allow drivers to return errors,
e.g. -EPROBE_DEFER if parent clocks have not been registered, yet.

To avoid init order woes for MVEBU clock drivers, we take care of
proper init order ourselves. This patch joins core-clk and gating-clk
init to maintain proper init order.

clk: keystone: gate: fix clk_init_data initialization

The clk_init_data struct is allocated in the stack. All members of
this struct should be initialized before using otherwise it will
lead to unpredictable situation as it can contain garbage.

Ultimately the clk->flag field contains garbage. In my case it leads
that flag CLK_IGNORE_UNUSED is set for most of clocks. As result a
bunch of unused clocks cannot be disabled.

So initialize flags in this structure too.

ARM: keystone: dts: fix clkvcp3 control register address

The address for control regs in clkvcp3 node is not correct and should
be 0x023500a8 instead of 0x0235000a8.

This lead to few unexpected behaviors while clocks were turned
of in absence of clk_ignore_unused

When patching gathers, we don't need to check against

iio: cm36651: Fix read/write integration time function.

This patch is fixed [read/write] integration time function.
cm36651 have integration time from 1 to 640 milliseconds.
But, print more then the thousand second. when call *_integration_time attribute.
Because read_integration_time function return IIO_VAL_INT.
read integration time function is changed return IIO_VAL_INT_PLUS_MICRO;
And then .write_raw_get_fmt callback function for parse a fixed-point number from a string.
Some description is revised milliseconds unit.
