By clearing the tamper bits and enabling access to the registers for all
code, just in case that this was set.  It keeps the clock running on
battery and the calibration setting.

Not all boards or BLE extensions have the flow control signals for BLE
available at suitable pins.  Actually none of the Adafruit extensions
match for flow control.

For consistency with the previous behaviour it is enabled by default.

There is a single UART clock for all devices, so switching it for one will
affect all devices used at that time.  This commit fixes that issue by
keeping the clock at a fixed value.

This fixed clock still supports the common baud rates between 300 and
921600 baud.

Prior to this commit, BTstack would only be notified of sent UART data when
the mp_bluetooth_hci_poll() function was called for some other reason, eg
because of incoming data over UART.  This is highly suboptimal.

With this commit, BTstack is now notified immediately after UART data has
been sent out.  This improves the multi_bluetooth/perf_gatt_char_write.py
performance test by about a factor of 10x for write-without-response, and
about 4x for write-with-response (tested on LEGO_HUB_NO6 as instance1).

1. Remove the skip for detecting support for polling user-defined objects
   as this is always possible now on all ports.
2. Don't print when the scheduled task runs as the ordering of this
   relative to the other prints is dependent on other factors (e.g. if
   using the native emitter).

iobase_ioctl expects that an ioctl method must return an integer, and will
raise otherwise.

This was tripping up aioble on Unix, where the new hybrid modselect.c
implementation will attempt to extract a file descriptor from the pollable
via ioctl(MP_STREAM_GET_FILENO).

However, ThreadSafeFlag's ioctl only supported MP_STREAM_POLL, and returned
None otherwise.

This makes it return `-1` (to match tests/extmod/select_poll_custom.py). It
should probably be `-22` (corresponding to MP_EINVAL), but the value is
never checked, and MP_EINVAL can be a different value on different ports.

Changes are:
- Disable internal flash storage and use the external QSPI for storage.
- Disable default bootloader entry mode.  The bootloader entry function
  exists in board_init.c.
- Remove OSC enable/disable macros (this board doesn't have an OSC).

This was previously hard-coded to "Micropy" / "Mass Storage" / "1.0".

Now allow it to be overridden by a board.

Also change "Micropy" to "MicroPy" and "1.0" to "1.00" to match stm32.

Add "CONFIG_BOOTLOADER_APP_ROLLBACK_ENABLE=y" to
ports/esp32/boards/sdkconfig.base so that all micropython esp32 images
support OTA rollback in the bootloader.  These images can then be converted
to OTA-capable images as required by user tools.

Also remove CONFIG_BOOTLOADER_APP_ROLLBACK_ENABLE=y from board-specific
sdkconfig files as this is now the default.

While cyw43 is deinitialized, an interrupt occurs.  That is handled with
these lines: ports/rp2/mpnetworkport.c#L59-L61 and as pendsv is disabled
while in network code, the poll function then just waits there.

When deinit has finished, the poll func is executed, but skipped:
src/cyw43_ctrl.c#L222-L225 this skips the `CYW43_POST_POLL_HOOK` which
would re-enable interrupts, but also reset `cyw43_has_pending`.

And in that state, the lightsleep code, will skip sleeping as it thinks
there is a network packet pending to be handled.

With this change applied, lightsleep works as expected when the wifi chip
is enabled, and when it's powered off.

The DHCP server broadcasts messages.  They are being sent via the default
netif which might be completely the wrong network.  We want to send
messages to the netif we got the original message from.
