Add "make submodules" to commands when building for the first time.
Otherwise, on a first time build, the submodules have not been checked out
and a lot of `fatal error: nrfx.h: No such file or directory` errors are
printed.
It practically does the same as qstr_from_str and was only used in one
place, which should actually use the compile-time MP_QSTR_XXX form for
consistency; qstr_from_str is for runtime strings only.
Don't clear the IPCC channel flag until we've actually handled the incoming
data, or else the wireless firmware may clobber the IPCC buffer if more
data arrives. This requires masking the IRQ until the data is handled.

This commit adds a new port "rp2" which targets the new Raspberry Pi RP2040
microcontroller.
The build system uses pure cmake (with a small Makefile wrapper for
convenience). The USB driver is TinyUSB, and there is a machine module
with most of the standard classes implemented. Some examples are provided
in the examples/rp2/ directory.
Work done in collaboration with Graham Sanderson.

It's enabled by default to retain the existing behaviour. A board can
disable this option if it manages mounting the filesystem itself, for
example in frozen code.

Changes are:
- refactor to use new _create_element function
- support extended version of MOUNT element with block size
- support STATUS element

This new element takes the form: (ELEM_TYPE_STATUS, 4, <address>). If this
element is present in the mboot command then mboot will store to the given
address the result of the filesystem firmware update process. The address
can for example be an RTC backup register.

Instead it is now passed in as an optional parameter to the ELEM_MOUNT
element, with a compile-time configurable default.

The superblock for littlefs is in block 0 and 1, but block 0 may be erased
or partially written, so block 1 must be checked if block 0 does not have a
valid littlefs superblock in it.
Prior to this commit, if block 0 did not contain a valid littlefs
superblock (but block 1 did) then the auto-detection would fail, mounting a
FAT filesystem would also fail, and the system would reformat the flash,
even though it may have contained a valid littlefs filesystem. This is now
fixed.
