The clock() function was introduced to provide free running clock for
the TPM2 library, which expects this clock to run with a millisecond
resolution.
This patch fixes the bug where the function in fact was returning the
clock running at a microsecond resolution.

This patch introduces HOST_CPPFLAGS to be used for all
objects being compiled with HOSTCC rather then the target
compiler.
Since glibc is not linked into the EC, no glibc include files
should be included in the EC code base. Hence, create local
definitions for clock_t and wchar_t that match what the glibc
include would have done, and remove some unneeded includes.
Due to very eager optimization, we have to give gcc a little
notch to not kick out memset.

TPM implementation requires a free running clock with granularity
better than a 10 us. clock_t definition comes from the toolchain

We'd defined them in a number of different files. This moves
definitions to timer.h, and uses them everywhere we have large delays
(since 10*SECOND is less typo-prone than 10000000).
Also add msleep() and sleep() inline functions. No need for mdelay()
or delay(), since any delays that long should use sleep funcs instead
of spin-waiting.

When we wake up from a deep sleep mode, the system timer clock might
have been stopped. We need to be able to set using another time source
(e.g. the RTC).

It is useful to implement timeouts like this:
start = get_time();
while (time_since32(start) < 1000)
...
Add a function to make this easy. Note that for efficiency we only
support a 32-bit return value which limits the timeouts to about an
hour.

To avoid calling get_time() when the caller already knows the value, add
a parameter to timestamp_expired().

Rather than open code this each time, create a function for this. The
wrap-around condition may not be needed, if the timer starts at zero,
since we have 64 bits to play with.

1) When frequency changes, reload the watchdog timer right away, or it
may expire before the next reload. (Only matters when re-enabling the
PLL.)
2) Split out the timer/task debug output used by the watchdog into
their own routines, instead of assuming it's safe to call the command
handlers. Also make the flushes in those print routines safe to call
from interrupt level.
