* 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.
