mimxrt: use lib/tinyusb/src/portable/chipidea/ci_hs/dcd_ci_hs.c instead of
lib/tinyusb/src/portable/nxp/transdimension/dcd_transdimension.c.
nrf: add a definition for the changed tud_task(). tud_task() is changed

src/device/usbd.h.
The items I know which are fixed with this version:
- Fix for the SAMD USB lock-up.
- Support the MIMXRT11XX series of MCUs.
- Fix a wrong pin definition for MIMXRT1050_EVKB.
Tested with the MIMXRT boards, rp2 Pico, SAMD boards, nrf board.

All ports that use mbedtls use the custom error messages in
mp_mbedtls_errors.c. This commit simplifies the build so that ports don't
need to explicitly add this file, it's now used by default when mbedtls is
enabled.
Signed-off-by: Damien George <damien@micropython.org>
The reasons to make this switch are:
- The axtls library is not being maintained/updated, mbedtls is.
- So CI and tests can run against mbedtls, which is now the main TLS
library used by the ports (eg stm32, rp2, mimxrt, esp32). Only esp8266
uses axtls.

Some devices, such as the LightBlue BTLE app on iOS, try to use Bluetooth 5
when connecting to a device. This means that they will send a
BLE_GAP_EVT_PHY_UPDATE_REQUEST message to shift to a new physical layer.
If this event isn't handled, LightBlue (and likely other Bluetooth 5.0
central devices) will try to connect and then fail, staying in
"Connecting..." state forever. This message should be replied to with
sd_ble_gap_phy_update, as documented in
drivers/bluetooth/s140_nrf52_6.1.1/s140_nrf52_6.1.1_API/include/ble_gap.h.

This gets basic machine.lightsleep([n]) behaviour working on the rp2 port.
It supports:
- Calling lightsleep without a specified period, in which case it uses xosc
dormant mode. There's currently no way to wake it up from this state,
unless you write to raw registers to enable a GPIO wake up source.
- Calling lightsleep with a period n in milliseconds. This period must be
less than about 72 minutes and uses timer alarm3 to wake it up.
The RTC continues to run during lightsleep, but other peripherals have
their clock turned off during the sleep.
It doesn't yet support longer periods than 72 minutes, or waking up from
GPIO IRQ.
Measured current consumption from the USB port on a PICO board is about
1.5mA when doing machine.lightsleep(5000), and about 0.9mA when doing
machine.lightsleep().

System config block contains hardware unrelated to USB. So calling

According to ST Errata ES0206 Rev 18, Section 2.2.1, on STM32F427x,
STM32F437x, STM32F429x and STM32F439x.
If the system tick interrupt is enabled during stop mode while certain
bits are set in the DBGMCU_CR, then the system will immediately wake
from stop mode.
Suggested workaround is to disable system tick timer interrupt when
entering stop mode.
According to ST Errate ES0394 Rev 11, Section 2.2.17, on STM32WB55Cx and
STM32WB35Cx.
If the system tick interrupt is enabled during stop 0, stop 1 or stop 2
while certain bits are set in DBGMCU_CR, then system will immediately
wake from stop mode but the system remains in low power state. The CPU
therefore fetches incorrect data from inactive Flash, which can cause a
hard fault.
Suggested workaround is to disable system tick timer interrupt when
entering stop mode.

- Integrate the I2S module and fix a rebase error.
- Use blocking transfer only for SPI. It's faster and interferes less with

Fixes issues #8344 and #8360.
