Remove Unused Code and Preprocessor Directives in RP2040 Port

Description

• Ever since the variables to enable/disable SMP were standardized to "configNUMBER_OF_CORES" in RP2040 updates/fixes from github.com/raspberrypi/FreeRTOS-Kernel #1193, there have been some code regions that use duplicate or inconsistent preprocessor conditions
• Consider the following example

#if ( configNUMBER_OF_CORES == 1 )
// some code
#else // implicitly configNUMBER_OF_CORES != 1 
    #if ( configNUMBER_OF_CORES != 1 )
        // always selected
    #else 
        // never selected (redundant/unnecessary)
    #endif
#endif

• In this case, the entire second set of preprocessor directives can be removed, with the always selected code staying and the redundant code also being deleted.
• Most of this was done for inline assembly code, in total for 4 instances total.
• Open to any feedback
