Add size and addr parameter to test "All" to override the default
value (4kB and STM32_DDR_BASE) used in tests with these optional
parameters: [size] or [addr].
When other optional parameters are present before [addr],
they are replaced by default value:
- [loop] = "1"
- [pattern] = "-" (new: force default pattern)
Example to use:
DDR>test 0 1 0x20000

- addr = start of DDR = 0xC0000000

This patch sets bufsize to STM32_DDR_SIZE and get_bufsize() selects

There maybe an overshoot:
- when disabling, then re-enabling vrefbuf too quickly
- or upon platform reset as external capacitor maybe slow
discharging (VREFBUF is HiZ at reset by default).
VREFBUF is used by ADC/DAC on some boards. An overshoot on the reference
voltage make the conversions inaccurate for a short period of time. So:
- Don't put the VREFBUF in HiZ when disabling, to force an active
discharge.
- Enforce a 1ms OFF/ON delay, also upon reset
Penalty is a 1ms delay is applied (even for a cold boot), when enabling
VREFBUF.

clk_composite_ops was shared between all devices in the composite clock
driver. If one clock had a feature (such as supporting set_parent) which
another clock did not, it could call a null pointer dereference.
This patch does three things
1. It adds null-pointer checks to all composite clock functions.
2. It makes clk_composite_ops const and sets its functions at compile-time.
3. It adds some basic sanity checks to num_parents.
The combined effect of these changes is that any of mux, rate, or gate can
be NULL, and composite clocks will still function normally. Previously, at
least mux had to exist, since clk_composite_get_parent was used to
determine the parent for clk_register.

CCF clocks should always use the struct clock passed to their methods for
extracting the driver-specific clock information struct. Previously, many
functions would use the clk->dev->priv if the device was bound. This could
cause problems with composite clocks. The individual clocks in a composite
clock did not have the ->dev field filled in. This was fine, because the
device-specific clock information would be used. However, since there was
no ->dev, there was no way to get the parent clock. This caused the
recalc_rate method of the CCF divider clock to fail. One option would be to
use the clk->priv field to get the composite clock and from there get the
appropriate parent device. However, this would tie the implementation to
the composite clock. In general, different devices should not rely on the
contents of ->priv from another device.
The simple solution to this problem is to just always use the supplied
struct clock. The composite clock now fills in the ->dev pointer of its
child clocks. This allows child clocks to make calls like clk_get_parent()
without issue.
imx avoided the above problem by using a custom get_rate function with
composite clocks.
