ARM Compiler 6.13 testing revealed linker errors pointing out
conflicting use of `__user_setup_stackheap` and
`__user_initial_stackheap` in some targets. Remove the unwanted
`__user_initial_stackheap` from the targets - the setup is
centralised in the common platform code.
Looking into this, a number of other issues were highlighted
* Almost all targets had `__initial_sp` hardcoded in assembler,
rather than getting it from the scatter file. This was behind
issue #11313. Fix this generally.
* A few targets' `__initial_sp` values did not match the scatter
file layout, in some cases meaning they were overlapping heap
space. They now all use the area reserved in the scatter file.
If any problems are seen, then there is an error in the
scatter file.
* A number of targets were reserving unneeded space for heap and
stack in their startup assembler, on top of the space reserved in
the scatter file, so wasting a few K. A couple were using that
space for the stack, rather than the space in the scatter file.
To clarify expected behaviour:
* Each scatter file contains empty regions `ARM_LIB_HEAP` and
`ARM_LIB_STACK` to reserve space. `ARM_LIB_STACK` is sized
by the macro `MBED_BOOT_STACK_SIZE`, which is set by the tools.
`ARM_LIB_HEAP` is generally the space left over after static
RAM and stack.
* The address of the end of `ARM_LIB_STACK` is written into the
vector table and on reset the CPU sets MSP to that address.
* The common platform code in Mbed OS provides `__user_setup_stackheap`
for the ARM library. The ARM library calls this during startup, and
it calls `__mbed_user_setup_stackheap`.
* The default weak definition of `__mbed_user_setup_stackheap` does not
modify SP, so we remain on the boot stack, and the heap is set to
the region described by `ARM_LIB_HEAP`. If `ARM_LIB_HEAP` doesn't
exist, then the heap is the space from the end of the used data in
`RW_IRAM1` to the start of `ARM_LIB_STACK`.
* Targets can override `__mbed_user_setup_stackheap` if they want.
Currently only Renesas (ARMv7-A class) devices do.
* If microlib is in use, then it doesn't call `__user_setup_stackheap`.
Instead it just finds and uses `ARM_LIB_STACK` and `ARM_LIB_HEAP`
itself.
After adding DEVICE_SERIAL_FC guards to serial_api.h
serial_set_flow_control is not available. In case of this
implementation, this function is a no-op and may be safely removed.
Imports working McuBoot for reset.
Updates microsec ticker driver.
Default baudrate is set to 115200 to see TF-M boot messages.
Stack top is set to scatter file dependent and not hard-coded.

These file changes provide small fixes for various targets
on MPS2 platform in order to work properly and pass all
Greentea test cases. The __initial_sp has been explicitly set
in the targets' startup files, and also INITIAL_SP has been
given a different value. The values have been extracted from
the specific targets' Application Note documentation.
Affected targets are: ARM_MPS2_M0, ARM_MPS2_M0P, ARM_MPS2_M3,
ARM_MPS2_M4 and ARM_MPS2_M7.

This commit represents the second stage of the low power implementations
that are required from Mbed 5.10 onwards. Besides the default hal
implementations (rtc_api.c and sleep.c), the PL031 RTC's native driver
needed to be added. Due to HW limitations in SSE-050 and the CM3DS,
Deep Sleep couldn't be implemented, therefore it is functionally
identical to Sleep (WFI).

This commit represents the first stage of the low power implementations
that are required from Mbed 5.10 onwards. The LP ticker has been
implemented using a CMSDK Dual Timer's both timers (HW prescaler needed
to operate in the specified frequency domain), whereas the us ticker
uses one CMSDK Timer. Besides the default hal implementations (lp_ticker.c
and us_ticker.c), the CMSDK Dual Timer's native driver needed to be added.
