Compatibility Concerns

Changes to Build System

...

* [#10605](https://github.com/apache/nuttx/pull/10605)  Implement ticket spinlock

A proposal to slove #1488

Implement ticket spinlock.

* [#10861](https://github.com/apache/nuttx/pull/10861) spinlock: Add spin_lock_init and spin_is_locked macro

align with Linux api naming.

* [#11102](https://github.com/apache/nuttx/pull/11102) sched: explicitly select the cpuload clock source configuration

Different configurations require different dependencies.
Explicitly select dependencies to avoid automatically selecting
inappropriate configurations.

* [#11334](https://github.com/apache/nuttx/pull/11334) stm32h7_adc: Dynamically set clock prescaler and BOOST

First commit is aligning naming and is a breaking change.

* [#10827](https://github.com/apache/nuttx/pull/10827) Improve adjtime() functionality

Prior pull request #9084 and issue #8858 added basic adjtime()
support for the SAMv7 platform.

This pull request adds support for STM32 platform.

In addition I have made a few changes to the adjtime() configuration
options:

1) Previously adjustments less than 1 microsecond per tick would be
   completely ignored. Now they are applied over a shorter period at
   a rate of 1 us per tick.

2) Previously CLOCK_ADJTIME_PERIOD was in units of 1/100th of second.
   Change to milliseconds to be more generally useful unit.
   Change setting name to CLOCK_ADJTIME_PERIOD_MS to make the unit change
   easier to notice.

3) Previously CLOCK_ADJTIME_SLEWLIMIT was in percentage.
   Most clock crystals have better accuracy than 1%, so the minimum slew
   rate was excessive. Change to CLOCK_ADJTIME_SLEWLIMIT_PPM with setting
   value in parts per million.

4) No need to use floating point math in clock_adjtime.c.

Impact

Users who have used CLOCK_ADJTIME_PERIOD and CLOCK_ADJTIME_SLEWLIMIT 
settings should update their configuration. New CLOCK_ADJTIME_PERIOD_MS is
10x the old period value, and new CLOCK_ADJTIME_SLEWLIMIT_PPM is 10000 times
the old slewlimit.
