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

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

That field is never used and, in most cases, is never initialized correctly.
This should have no impact to anything with the possible exception of free-running drivers.
Verified using CI builds only.
The comments at the top of the file say this:
```
This will be automatically registered
* - AXI SRAM is a 512kb memory area. This will be automatically registered
* with the system heap in up_allocate_heap, all the other memory
* regions will be registered in arm_addregion().
```
but the implementation was using SRAM123 instead. Furthermore, arm_addregion then re-adds SRAM123 again.

This change makes it so that the timeout is set as part of the SDIO_WAITENABLE call instead of the SDIO_EVENTWAIT call. By doing so, you eliminate all opportunity for a race condition.
