Subject: [PATCH v4 0/2] wifi: mwifiex: Fix RF calibration data handling issues

This patch series addresses two related issues with downloading RF
calibration data in the mwifiex driver. The first patch resolves the
problem of calibration data being prematurely released before the
download process. The second patch focuses on restoring the functionality
to download RF calibration data from a file, which was broken by a previous
commit.

These fixes ensure proper handling of calibration data while avoiding any
impact on downloading configuration data from the device tree.

Typically, calibration data comes from OTP/EEPROM. This patch merely
enables the functionality to download CAL data to the firmware from a file
and does not require backporting to stable versions.

**Changelog**:
v4:
- Patch 1: Clarified the title and included the Fixes tag.
- Patch 2: Refactored the patch to ensure that changes for restoring
file-based RF calibration data downloads do not impact the functionality
for downloading configuration data from the device tree. Added detailed
explanation about the potential impact on device tree-based calibration
data downloads.

v3:
- Split the patch into two separate parts for better clarity.
- Improved commit messages to provide more context about the issues being
addressed.

v2:
- Expanded the commit messages with detailed descriptions of the problems
and their impact.
- Highlighted the premature release of calibration data before the download
process.

v1:
- Initial submission. Focused on correcting the command format for
downloading calibration data.
