stm32h7: Serail Add Power Managment (Untested)
arch: Allocate the space from the beginning in up_stack_frame
and modify the affected portion:
1.Correct the stack dump and check
2.Allocate tls_info_s by up_stack_frame too
3.Move the stack fork allocation from arch to sched

For unknown reasons this message may interferre with the calibration
procedure and result in invalid calibariton data.
We leave only a message informing about the end of the the calibration.
The problem was observed for STM32G4 + IHM16M1.
I've seen a module with 16 bytes .rodata alignment for xmm operations.
It was getting SEGV on sim/Linux because of the alignment issue.
The same module binary seems working fine after applying this patch.
Also, tested on sim/macOS and esp32 on qemu,
using a module with an artificially large alignment. (64 bytes)
Change the logic for allocating user heap for PROTECTED_BUILD:
- Don't rely on SRAM1_END alignment
- Make better use of MPU subregions when allocating the heap
- Don't duplicate the calculation of user heap start in kernel heap
allocation; use the previous calculation directly

Summary:
- I noticed that stack corruption happens due to recent refactoring
- This commit fixes this issue
Impact:
- SMP only
Testing:
- Tested with maix-bit:smp (QMU and dev board)

Some ESP32 GPIO pins (2, 4, 12, 13, 25, 27, 32) weren't accepting
pull-up/pull-down resistors. These pins are RTC GPIO pins and need
to have pull-up/pull-down configured in the RTC registers.

All supported arch uses a push-down stack:
The stack grows toward lower addresses in memory. The stack pointer
register points to the lowest, valid working address (the "top" of
the stack). Items on the stack are referenced as positive(include zero)
word offsets from sp.
Which means that for stack in the [begin, begin + size):
1.The initial SP point to begin + size
2.push equals sub and then store
3.pop equals load and then add
