hw/timer/stellaris-gptm: Use Clock input instead of system_clock_scale

The stellaris-gptm timer currently uses system_clock_scale for one of
its timer modes where the timer runs at the CPU clock rate. Make it
use a Clock input instead.

We don't try to make the timer handle changes in the clock frequency
while the downcounter is running. This is not a change in behaviour
from the previous system_clock_scale implementation -- we will pick
up the new frequency only when the downcounter hits zero. Handling
dynamic clock changes when the counter is running would require state
that the current gptm implementation doesn't have.

hw/timer/armv7m_systick: Use clock inputs instead of system_clock_scale

Now that all users of the systick devices wire up the clock inputs,
use those instead of the system_clock_scale and the hardwired 1MHz
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.
