hw/timer/armv7m_systick: Update clock source before enabling timer

Starting the SysTick timer and changing the clock source a the same time
will result in an error, if the previous clock period was zero. For exmaple,
on the mps2-tz platforms, no refclk is present. Right after reset, the
configured ptimer period is zero, and trying to enabling it will turn it off
right away. E.g., code running on the platform setting

SysTick->CTRL = SysTick_CTRL_CLKSOURCE_Msk | SysTick_CTRL_ENABLE_Msk;

should change the clock source and enable the timer on real hardware, but
resulted in an error in qemu.

Now that all users of the systick devices wire up the clock inputs,

value for the reference clock.

This will fix various board models where we were incorrectly
providing a 1MHz reference clock instead of some other value or
instead of providing no reference clock at all.

hw/timer/armv7m_systick: Add input clocks

The v7M systick timer can be programmed to run from either of
two clocks:
* an "external reference clock" (when SYST_CSR.CLKSOURCE == 0)
* the main CPU clock (when SYST_CSR.CLKSOURCE == 1)

Our implementation currently hardwires the external reference clock
to be 1MHz, and allows boards to set the main CPU clock frequency via
the global 'system_clock_scale'. (Most boards set that to a constant
value; the Stellaris boards allow the guest to reprogram it via the
board-specific RCC registers).

As the first step in converting this to use the Clock infrastructure,
add input clocks to the systick device for the reference clock and
the CPU clock. The device implementation ignores them; once we have
made all the users of the device correctly wire up the new Clocks we
will switch the implementation to use them and ignore the old
system_clock_scale.

This is a migration compat break for all M-profile boards, because of
the addition of the new clock objects to the vmstate struct.

hw/timer/armv7m_systick: Rewrite to use ptimers

The armv7m systick timer is a 24-bit decrementing, wrap-on-zero,
clear-on-write counter. Our current implementation has various
bugs and dubious workarounds in it (for instance see
https://bugs.launchpad.net/qemu/+bug/1872237).

We have an implementation of a simple decrementing counter
and we put a lot of effort into making sure it handles the
interesting corner cases (like "spend a cycle at 0 before
reloading") -- ptimer.

Rewrite the systick timer to use a ptimer rather than
a raw QEMU timer.

Unfortunately this is a migration compatibility break,
which will affect all M-profile boards.

Among other bugs, this fixes
https://bugs.launchpad.net/qemu/+bug/1872237 :
now writes to SYST_CVR when the timer is enabled correctly
do nothing; when the timer is enabled via SYST_CSR.ENABLE,
the ptimer code will (because of POLICY_NO_IMMEDIATE_RELOAD)
arrange that after one timer tick the counter is reloaded
from SYST_RVR and then counts down from there, as the
architecture requires.

hw/timer/armv7m_systick: assert that board code set system_clock_scale

It is the responsibility of board code for an armv7m system to set
system_clock_scale appropriately for the CPU speed of the core.
If it forgets to do this, then QEMU will hang if the guest tries
to use the systick timer in the "tick at the CPU clock frequency" mode.

We forgot that in a couple of our boards (see commits ce4f70e81ed23c93f,
e7e5a9595ab1136). Add an assertion in the systick reset method so
we don't let any new boards in with the same bug.

Include migration/vmstate.h less

In my "build everything" tree, changing migration/vmstate.h triggers a
recompile of some 2700 out of 6600 objects (not counting tests and
objects that don't depend on qemu/osdep.h).

hw/hw.h supposedly includes it for convenience. Several other headers
include it just to get VMStateDescription. The previous commit made
that unnecessary.

Include migration/vmstate.h only where it's still needed. Touching it
now recompiles only some 1600 objects.

Like most of the v7M memory mapped system registers, the systick
registers are accessible to privileged code only and user accesses
must generate a BusFault. We implement that for registers in
the NVIC proper already, but missed it for systick since we
implement it as a separate device. Correct the omission.
