Improvements are:
- Default period is 1000ms with callback disabled.
- if period is not specified then it's not updated (previously, if period
was not specified then it was set to -1 and running the timer callback as
fast as possible, making the REPL unresponsive).
- Use uint64_t to compute delta_ms, and raise a ValueError if the period is
too large.
- If callback is not specified then it's not updated.
- Specifying None for the callback will disable the timer.

Added board definition for the Sparkfun MicroMod RP2040.
Mostly followed the format for pins from the MicroMod nRF52840 board
definition, as MicroMod tries to standardize pins across
microcontrollers.
The PIO state machines on the RP2040 have 4 word deep TX and RX FIFOs. If
you only need one direction, you can "merge" them into either a single 8
word deep TX or RX FIFO.
We simply add constants to the PIO object, and set the appropriate bits in
`shiftctrl`.
Resolves#6854.

Commit 8a917ad2529ea3df5f47e2be5b4edf362d2d03f6 added the gpio_reset_pin()
call to make sure that pins that were used as ADC inputs could subsequently
be used as digital IO. But calling gpio_reset_pin() will enable the
pull-up on the pin and so pull it high for a brief period. Instead use
rtc_gpio_deinit() which will just reconfigure the pin as a digital IO and
do nothing else.
Fixes issue #7079 (see also #5771).

This is handy for remote characteristics because it allows for
the PacketBuffer binding code to have the correct max size. This
PR also adds checks so we don't write outside the outgoing buffer.
For an unconnected TCP socket, poll should return WR|HUP and read should
raise ENOTCONN. This is implemented by this commit and now the following
tests pass on esp32: extmod/usocket_tcp_basic.py,
net_hosted/connect_poll.py.

This change allows running the tests in tests/basics/ without any failures
(but some tests are still skipped).

This fixes `error: variable 'subpkg_tried' might be clobbered by 'longjmp'
or 'vfork' [-Werror=clobbered]` when compiling on ppc64le and aarch64 (and
possibly other architectures/toolchains).
