HAL CRC: Add DEVICE_CRC macro to doxygen files

HAL CRC: K64F: Set output width based on input width, not the polynomial

HAL CRC: Fix code to match coding conventions

Add support for final_xor for K64F Hardware CRC

HAL CRC: Add bit width parameter to crc_config_t

Add CRC configuration options to HAL API

HAL CRC: Return early when calling compute with null or 0 size buffer

Remove support for 7/8 bit CRC polynomials for K64F

Fix CRC class coding conventions

Add K64F Hardware CRC reference implementation ...

- Add support for all currently defined polynomials
- Add 'CRC' flag to targets.json for K64F profile

Adapt MbedCRC class to support Hardware CRC ...

- Move CRC polynomial enum into HAL layer, so it's accessible from platform
  implementations

- Add enum to CRC class to indicate which mode the CRC class should use:
  HARDWARE, TABLE, or BITWISE

- Add calls to HAL Hardware CRC API to each of the compute functions when the
  class is in HARDWARE mode.

- Add missing constructor call to template constructor, and remove const from
  delegating constructor.

Add Hardware CRC HAL API specification headers ...

Define the HAL API header for the Hardware CRC module. This set of functions
allows hardware acceleration of a subset of CRC algorithms for supported
platforms by providing access to the hardware CRC module of certain platforms.

The API is defined as four separate functions:

  - hal_crc_is_supported(polynomial)

    Indicates to the caller if the specific CRC polynomial is supported.

  - hal_crc_compute_partial_start(const uint32_t polynomial)

    Initializes the hardware CRC module with the given polynomial.

  - hal_crc_compute_partial(*data, size)

    Writes an array of bytes to the CRC module to be appended to the calculation

  - hal_crc_get_result()

    Applies the final transformations to the data and returns the result to the
    caller.

Increased wait time to allow device to sleep ...

With small wait time at the start, chances are that device does not
enter sleep and idle time is zero. Increasing wait time to make sure
device goes to sleep.
