Add praline gpio (#3218)

* Implement antenna bias control for Praline and update GPIO configurations
* Add GPIO power management functions and update board initialization for Praline
* Refactor power management functions for Praline and update GPIO configurations
* Update GPIO configurations for Praline and enable power control pins. AA_EN enabled
* Refactor GPIO configuration for Praline: update array size definitions and clean up comments
* Add P1 and P2 control functions for PRALINE
* Introduced P1_Function and P2_Function enums in ClockManager to manage multiplexer control.
* mplemented set_p1_control and set_p2_control methods for configuring P1 and P2 control pins based on specified functions.
* Updated clock_manager.hpp and clock_manager.cpp to include new functionality.
* Modified MAX2837 and MAX2839 initialization to conditionally configure GPIO based on PRALINE.
* Adjusted RFFC507x and RFFC507x_SPI initialization to include GPIO setup for PRALINE.
- Refactored RF path initialization to remove unnecessary GPIO setup.
- Updated board configuration for PRALINE to reflect new GPIO settings and pin configurations.
- Cleaned up FPGA bridge code by removing unused pin configuration functions.
- Adjusted SCU array size in pal_lld.h for PRALINE.
- Enhanced hackrf_gpio.hpp to define multiplexer control pins for PRALINE.
- Modified LED setup to accommodate active-low configuration for PRALINE.

* Refactor GPIO and power control functions

- Removed unused power control function declarations from board.h.
- Enhanced gpio.hpp with new pin setup functions and GPIO control structures for PRALINE.
- Consolidated multiplexer control pin definitions into gpio_control namespace.
- Moved power control function implementations to gpio.cpp, including detailed VAA power management logic.
- Updated power control functions to handle both PRALINE and HackRF R9 configurations.
- Cleaned up hackrf_gpio.hpp by removing redundant multiplexer control definitions.

* Refactor GPIO control for PRALINE: update MAX2831 and RFFC507x configurations, add new GPIO mappings

* Refactor GPIO configurations for PRALINE: update anti-aliasing filter pin mapping, enhance LED setup logic, and add placeholder GPIO entries.

* Refactor GPIO configurations for PRALINE: update LED mappings and remove unused anti-aliasing filter GPIO entry.
