This fix avoid a long waiting loop in rtc_write function,
which was not acceptable in TICKLESS context.
Implementation comments added.
Global variable name has been updated for easier maintenance:
- LPTICKER_counter is the U32 continuous tick counter
- LPTICKER_RTC_time is the RTC time used to get the time difference
between rtc_read_lp() calls

reason: `time()` returns a float. So the fix is to force it to be an `int`.

Missing CellularSocket constructor caused uninitialized values to be used.
Also changed comparision macros to ASSERT_EQ as suggested by GoogleTest guide.
Need to ensure the transmission has been started before sending a STOP condition.
Issue found on the NUCLEO_H743ZI due certainly to the high-speed clock used.
But this is normally needed also on all STM32 devices using the I2C peripheral version 2.
### Description
2 calls to `notify.cc_verbose` used the a FileRef object in place of
the file's name. Other calls to `notify.cc_info` would use just the
file name. This PR changes these 2 calls to be consistant with the rest.

The NRF51 post build hook finds it's hex files using the Resources
object. This PR fixes the corner case where the hex files within a
project have a name!=path (This really only happens online).

Test case was assuming that secure and unsecure SSID were on different
channels.
This is not a requirement and it should be OK to run on same channel.
Fixed the testcase by using +1 on channel number to get a wrong channel.
pwmout:
Used SystemCoreClock
Serial fuart:
SERIAL_5 & SERIAL_3 have same CTS pin (PA7), only function register is different (4 & 2).
pinmap_peripheral() will always return first match from the map.
Hence changed as, if SERIAL_5 is used, then pinmap_peripheral() should return SERIAL_5 (function register 2 to be set).
2.4GHz and 5GHz channels might be using the same SSID. Wifi scan
might also fail occasionally to find secure- and unsecure channels
on same scan so lets not assume that we'll find both.
- Change the default file format to binary for all targets, even though some targets need hex as app format, updater always needs bin for now
- Unify the file name generation from generator side and usage side for the update bin
To enable the feature US_TICKER, file is newly implemented with Timer B, which has proper clock prescale and free running after match interrupt.
Old us_ticker driver file (Timer A) is producing up to 100us tolerance, which causes to fail US_TICKER feature.
Hence, changed the peripheral ticker A to B.
Currently the return value of flash_get_page_size() is 1 since the min size per one writing is 1 byte by Flash spec.
However, I noticed that this value causes a enormous write time When writing large data such as FW update.
So I revised this value to 8 byte by considering the writing time, memory alignment and memory hole.
I changed _page_program() func because "buf" which is an argument of data_send() for writing must be a RAM address in order to operate in SPI mode.
(ex: if it is ROM table data, writing will be failure.)
Also, I changed the period of interrupt disable/enable at _page_program() func and _sector_erase() func because lock period is too long.
Correctly detect and handle the low power run mode when entering and exiting sleep mode.
The generic `hal_sleep` implementation tries to exit LPR mode always, resulting in a spin-loop during a critical section (disabled IRQ).
The new approach returns from LPR to Run mode if enabled (LPR bit set), enters sleep, and resets to the original state on wakeup (WFI).
Replace wait_us with nu_busy_wait_us in lp_ticker since wait_us is not allowed in sleep test
which would suspend us ticker layer on which wait_us relies. nu_busy_wait_us is implemented
by calling us ticker HAL API directly rather than relying on us ticker layer.
There are scenarios where putc is called within a critical section, e.g
to log ASSERTs in early initialization code. The interrupts being
disabled here prevents the handlers for the UARTE from executing.
This breaks the tx_in_progress flag based approach. The tx_in_progress
never gets reset. Poll on the TXDRDY instead.
It can be recreated with a simple program as shown here:
