* Unify the system peripheral
Whilst the PCR, SYSTEM and DPORT peripherals are different, we currently
use them all in the same way. This PR unifies the peripheral name in the
hal to `SYSTEM`. The idea is that they all do the same sort of thing, so
we can collect them under the same name, and later down the line we can
being to expose differences under an extended API.
The benifits to this are imo quite big, the examples now are all identical,
which makes things easier for esp-wifi, and paves a path towards the
multichip hal.
Why not do this in the PAC? Imo the pac should be as close to the
hardware as possible, and the HAL is where we should abstractions such
as this.

* WIP: common/spi: Implement `SpiDevice`
to get shared access to an SPI bus directly via the HAL.
* WIP: common/spi: add SpiBusDevice::new
to create instances via a function call.
* esp32/examples: Add example for spi device trait
* common/spi: Finish "SpiDevice" implementation
for esp32. Abandons the approach of having the user pass in some generic
mutex in favor of creating the Mutex as part of the API so it isn't
exposed to the user in the first place.
* common/spi: Add more thorough docs
* esp32/examples: Fix example for eh1 "SpiDevice"
* common/spi: Implement `SpiDevice` for xtensa arch
and move the code into a submodule that is fenced with conditional
compilation directives.
* esp32/examples: Update spi device example
to the changed APIs for the timers and clocks, and add more transmission
tests to the example code.
* common/spi: Create devices from buscontroller
directly, instead of offering only the `new` method.
* common/spi: Finish `SpiBusDevice` trait
from embedded-hal 1.0.0-alpha.8.
* esp32: Update `SpiBusDevice` usage example.
* common/spi: Fix mutex types for xtensa32 esp
because the esp32/esp32s3 can use `SpinLockMutex`, whereas the esp32s2
has access only to `CriticalSectionMutex`.
* common/spi: Implement `SpiBusDevice` for riscv
based esp32c3.
* general: Add examples for spi device loopback
to all esp variants.
* common: Use esp_backtrace in spi_eh1_device examples
* common/spi: Update module documentation.
* common/spi: Use `critical_section::Mutex`
to unify locking across all esp variants.
* esp32c3-hal: Fix spi device example
* esp32c3/examples: Fix typo in used spi pins
