Initial broadcom port for Raspberry Pi
This targets the 64-bit CPU Raspberry Pis. The BCM2711 on the Pi 4
and the BCM2837 on the Pi 3 and Zero 2W. There are 64-bit fixes
outside of the ports directory for it.

There are a couple other cleanups that were incidental:
* Use const mcu_pin_obj_t instead of omitting the const. The structs
  themselves are const because they are in ROM.
* Use PTR <-> OBJ conversions in more places. They were found when
  mp_obj_t was set to an integer type rather than pointer.
* Optimize submodule checkout because the Pi submodules are heavy
  and unnecessary for the vast majority of builds.

Turn on unicode for FATFS
This also tweaks the repr for unicode strings to only escape a few
utf-8 code points. This makes emoji show in os.listdir() for
example.

Also, enable exfat support on full builds.

Jeff Epler eef742bf45 oofatfs: Remove _FS_DISK_READ_ALIGNED
This workaround is no longer needed, so it can be removed.

Closes: #2332

Jeff Epler a484a93b29 nRF: disk_read must be 4-byte aligned
.. a requirement that oofatfs needs to be taught to respect.

This problem can be demonstrated with the following snippet, except
that the related file ("test.bin") must also be contiguous on the
filesystem.  You can ensure this by reformatting your device's filesystem
before testing, then copying any single file bigger than 4kB to test.bin.

    f = open("test.bin", "rb")
    f.seek(2048)
    b = bytearray(2048)
    v = memoryview(b)
    f.readinto(v[909:])

Closes: #2332

Noralf Trønnes 28383afa11 shared-module/os: Fix os.mkdir('a/b')
This fixes commit a99f9427420d("'/' and '\' are also acceptable ends of the path now") which broke mkdir.
The problem is where the directory name is a single letter like this:
>>> os.mkdir('a')
>>> os.mkdir('a/b')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
OSError: [Errno 17] File exists
>>> os.mkdir('a/bb')
>>>

I wasn't smart enough to fix this in the oofatfs library, so I did it in the os shared module by
creating a path lookup function for the os methods that only deals with directories. I reverted
the library change introduced by the aforementioned commit.

This means that os.stat and os.rename can't handle trailing slashes. This is to avoid allowing
filenames with trailing slashes to pass through. In order to handle trailing slashes for these
it would be necessary to check if it really is a directory before stripping. I didn't do this
since the original issue was to make os.chdir tolerate trailing slashes.

There's an open MicroPython issue #2929 wrt. trailing slashes and mkdir.
