This commit overhauls the CC1101 RF driver to address physical hardware constraints, prevent register wrap-around overflows, and support accurate dBm power scaling via the standard IOCTL interface. What this change does: 1. Adds WLIOC_MSK and WLIOC_4FSK modulation support in `ioctl.h` and driver. 2. Replaces static PATABLE initialization with a dynamic Ramp-up curve generator `cc1101_ioctl_apply_power()` based on lab calibration data. 3. Modifies WLIOC_SETTXPOWER and WLIOC_GETTXPOWER to process actual dBm values with a nearest-match algorithm instead of raw array indices. 4. Removes DEBUGASSERT on user-space IOCTL pointers and replaces them with strict -EFAULT checks. 5. Implements saturation clamping (e.g., mantissa to 256-511) to prevent bitrate and frequency deviation calculation overflows. 6. Rebuilds volatile PATABLE memory upon SLEEP mode wake-up. Why it is necessary & what it fixes: - Fixes severe OOK modulation distortion and FSK spectral splatter caused by statically assigned PATABLE indices. - Fixes potential kernel panic in flat builds when IOCTL receives a NULL pointer from user space. - Fixes register wrap-around (silent failures) when users pass out-of-bounds baud rate or FDEV values. - Prevents RF silence after SLEEP mode due to PATABLE volatility. - Resolves inaccurate power output when changing frequencies dynamically. Impact: Changes the behavior of CC1101 TX power and modulation IOCTLs to strictly comply with standard `wlioc` definitions. Improves overall driver stability and hardware safety.
