    ld: pru: Increase the default memory region sizes
    
    The default memory region sizes for PRU were set somewhat arbitrarily to
    the sizes of the most popular BeagleBone board with AM33x SoC.  But the
    PRU toolchain documentation has always instructed to use SoC-specific
    spec files to override the defaults and set the correct memory sizes [1].
    
    The small default memory sizes can cause IMEM memory region overflow
    even for simple printf("Hello world") programs, as usually done by
    Autotools checks.  The stdio is simply too big to fit in 8K
    instruction memory.  This can confuse the check and lead to wrong
    feature selection during configure [2].
    
    Fix by bumping the default DMEM and IMEM memory sizes.
    
    There is no need to backport this patch.  Issue was caught with a
    feature-rich newlib build used for daily CI.  The release builds of the
    PRU toolchain use stripped newlib configuration, which does not overflow
    the IMEM region, even for 8K.
