Chip L. 4aca170070 wireless/cc1101: Make SPI burst and single frequencies configurable 
This patch introduces CONFIG_CC1101_SPIFREQ_BURST and
CONFIG_CC1101_SPIFREQ_SINGLE to Kconfig, allowing users to override
the default SPI frequencies for the CC1101 wireless driver.

Previously, these values were hardcoded to 6.5 MHz and 9.0 MHz
respectively. While these are safe defaults for many setups, specific
hardware designs, high routing capacitance, or platforms utilizing
internal GPIO switching matrices (such as the ESP32) can suffer from
signal integrity degradation at these speeds. By exposing these to
Kconfig, users can easily adjust the clock speeds to match their
hardware capabilities without modifying the core driver source.

Impact:
- Build: Adds two new Kconfig options under WL_CC1101.
- Runtime: Retains 6.5 MHz / 9.0 MHz defaults. Behavior only changes
  if overridden via menuconfig.

Testing:
- Built with default values and custom Kconfig overrides.
- Hardware Testing: Tested on a sub-optimal platform utilizing an
  internal GPIO matrix (ESP32). The CC1101 failed to load at the
  default 6.5/9.0 MHz due to signal integrity issues. Downclocking
  the frequencies to 4.0 MHz via Kconfig successfully restored
  signal integrity and allowed the driver to initialize and operate
  normally.
