Without free-up of peripheral pins, peripheral pins of the same peripheral may
share by multiple ports after port iteration, and this peripheral may fail with
pin interference.
In Nuvoton, only new-design chips support GPIO input pull-high/pull-low modes.
Targets not supporting this feature are listed below:
- NUMAKER_PFM_NANO130
- NUMAKER_PFM_NUC472
- NUMAKER_PFM_M453
Fix logic error on replying NACK at the end of transfer.
This is also to fix FPGA CI test mbed_hal_fpga_ci_test_shield-i2c/
i2c - test single byte read i2c API.
Better IP initialization sequence:
1. Configure IP pins
2. Select IP clock source and then enable it
3. Reset the IP (SYS_ResetModule)
NOTE1: IP reset takes effect regardless of IP clock. So it doesn't matter if
IP clock enable is before IP reset.
NOTE2: Non-configured pins may disturb IP's state, so IP pinout first and then
IP reset.
NOTE3: IP reset at the end of IP initialization sequence can cover unexpected
situation.
The stack memory is a `void*` which creates a warning when using
the `delete[]` operator because it is unable to call the destructor of
of an unknown object type.
On Nuvoton targets, lp_ticker_set_interrupt(...) needs around 3 lp-ticker
ticks to take effect. It may miss when current tick and match tick are very
close (see hal/LowPowerTickerWrapper.cpp). Enlarge LPTICKER_DELAY_TICKS to
4 from 3 to address this boundary case.
This test requires total latency (tot = h/w + s/w) (wakeup from deepsleep) be
under 1ms. To check the issue, measure total latency on Nuvoton targets:
TARGET EXP(us) EXP+TOL(us) ACT(us)
NANO130 42000 43000 42939
NUC472 42000 43000 42236
M453 42000 43000 43274
M487 42000 43000 42877
M2351 42000 43000 43213
Checking h/w spec, h/w latency (wakeup time from normal power-down mode) on
M487/M2351 is just 1us (n/a on other targets). S/W latency plays the major
part here.
S/W latency relies on system performance. On Nuvoton targets, 'LPTICKER_DELAY_TICKS'
possibly complicates the test. Anyway, to pass the test, add extra 1ms latency
(deep-sleep-latency) in targets.json for Nuvoton targets.

In some multithread cases there is possibility that process_oob function
was called after ATHandler was deleted. Fix is to wait if oob processing
is ongoing.

Replace the sleep_manager_can_deep_sleep() with !_deep_sleep_locked.
Indeed, if we know we've taken the lock because we're using us_ticker,
no need to do the early wake.
Updated comments accordingly.
When next SysTimer wake-up is scheduler far enough, always consider
that deep sleep may be entered and program an early wake-up.
So that even if deep sleep is only allowed some time later, it can be
entered. If not doing this, then the deep sleep would be prevented by
SysTimer itself and may not be entered at all.
This has been proved to happen in a simple blinly example.
Mbed TLS's export keys callback requires the hello.random (for both
server and client) to be const. Make the callbacks in Mbed OS that use
the key export feature use const to match.

NOTE1: USB UART is partitioned for non-secure world. Secure world still can share
it with limit that its interrupt cannot use in secure world.
NOTE2: In secure world, USB UART is only for Greentea and STDIO. Developers shouldn't
use it for other purposes.
