    linker_script: move .data section to bl_common.ld.h · caa3e7e0

    Move the data section to the common header.
    
    I slightly tweaked some scripts as follows:
    
    [1] bl1.ld.S has ALIGN(16). I added DATA_ALIGN macro, which is 1
        by default, but overridden by bl1.ld.S. Currently, ALIGN(16)
        of the .data section is redundant because commit 41286590
    
    
        ("Fix boot failures on some builds linked with ld.lld.") padded
        out the previous section to work around the issue of LLD version
        <= 10.0. This will be fixed in the future release of LLVM, so
        I am keeping the proper way to align LMA.
    
    [2] bl1.ld.S and bl2_el3.ld.S define __DATA_RAM_{START,END}__ instead
        of __DATA_{START,END}__. I put them out of the .data section.
    
    [3] SORT_BY_ALIGNMENT() is missing tsp.ld.S, sp_min.ld.S, and
        mediatek/mt6795/bl31.ld.S. This commit adds SORT_BY_ALIGNMENT()
        for all images, so the symbol order in those three will change,
        but I do not think it is a big deal.
