v0.6.0

BREAKING Remove type states from the following drivers:

• FlexPWM
• GPT
• PIT
• LPI2C
• LPUART
• LPSPI
• ADC (10xx)
• SAI
• GPIO, RGPIO

After construction, the type no longer tracks its pins or peripheral instances.
To type check peripheral instances against pins, construct types using
with_pins.

BREAKING The FlexPWM refactor removes dedicated types for Submodules and
Outputs. Users should program directly against the Pwm type.

BREAKING The PIT driver no longer models channels as dedicated objects.
Users should program directly against the Pit type.

BREAKING There is no support for unproven embedded-hal 0.2 traits. The
eh02-unproven feature is removed.

BREAKING There is no support for rand_core traits. The rand_core
feature is removed.

BREAKING The TRNG and TEMPMON drivers use core::task::Poll instead
of nb::Result.

BREAKING Remove the dependency on imxrt-usbd and the usbd module.
Users should select their preferred versions of imxrt-usbd, usb-device,
and other class packages.

BREAKING Update imxrt-rs dependencies that affect the public API:

• imxrt-ral 0.6
• iomxrt-iomuxc 0.3
• imxrt-dma 0.2

Additionally, update third-party dependencies in the public API:

• bitflags 2.11
• embedded-io 0.7

BREAKING Remove deprecated APIs

• clko2::Selection::TracClk
• lpspi::Disabled::{set_mode, set_watermark}

BREAKING Change the LPSPI driver:

• LpspiError::{Busy, NoData} are removed as possible LPSPI errors.
• There is no more PCS0 type state associated with the LPSPI bus.
• FifoStatus has public members for TX and RX FIFO capacities.
• Transaction fields are no longer public. Use the set_* (const) methods
  to set the fields on a Transaction object.

Introduce a hardware chip select and SPI mode into each LPSPI transaction.
Add an LPSPI configuration for hardware chip selects.

The Lpspi provides an implementation of embedded-hal 1.0 SpiBus. You may use
the SpiBus with either a software- or hardware-managed chip select, depending
on how you choose to mux LPSPI pins.

BREAKING The following peripherals are not available on the 1180. Therefore,
they are no longer considered common. However, their APIs are unchanged, and they
are still exposed when building with a chip feature.

• gpio
• pit
• snvs
• timer

BREAKING Remove the timer module, including most embedded-hal 0.2 blocking
delay implementations.

BREAKING Upgrade to Rust 2024.

Introduce an imxrt1180 feature to support the RT1180 series.

Add a defmt feature targeting version 1.0. When enabled, select imxrt-hal
types can be formatted with defmt.

Export the SAI driver for 1170 MCUs. Fix SAI FPACK enumerated values. Ensure
SAI tracks configured pins, even if users prefer without_pins.

Add SAI DMA support. DMA targets the lowest-numbered enabled data line for
each direction; multiple data lines are not supported by DMA.
