The tcl script src/target/startup.tcl has already the proper
centralized support to wait for all targets to halt after the
command "reset halt". The extra wait in cortex_a_deassert_reset()
is not required.
This extra wait is also an issue for multi-core support, because
waiting for one core to halt can delay the halt request to the
other cores.
Replace the indirect call to cortex_a_halt(), that embeds the wait
for halt, with a low-level halt sequence.
The on-going work on the reset framework is compatible with this
change; in fact it keeps in startup.tcl the wait for targets to
halt, even if current code proposal for cortex_a simply removes
the function cortex_a_deassert_reset().

The usleep() function, and its associated useconds_t type
specifier, has been obsoleted by POSIX.1-2008.
OpenOCD has 28 call to usleep(), that should be migrated to the
replacement nanosleep(), but due to the different prototype
int nanosleep(const struct timespec *req, struct timespec *rem);
this can take some effort.
The type useconds_t is used in only one case, where it's used both
as parameter of usleep() and as value passed to LOG_DEBUG(). Due
to different implementation of useconds_t, there are cases that
trigger a compile warning in LOG_DEBUG() when useconds_t is more
than 32 bit.
E.g. with unistd.h in MinGW 4.x, useconds_t is defined as unsigned
long, thus being 32 or 64 bits depending on the target.
Replace the only instance of useconds_t.
