fix(plat/marvell/a3k): fix printing info messages on output

INFO() macro for every call prepends "INFO:   " string. Therefore
current code prints unreadable debug messages:

    "INFO:    set_io_addr_dec 0 result: ctrl(0x3fff3d01) base(0x0)INFO:    "
    "INFO:    Set IO decode window successfully, base(0xc000)INFO:     win_attr(3d) max_dram_win(2) max_remap(0)INFO:     win_offset(8)"

Fix it by calling exactly one INFO() call for one line. After this
change output is:

    "INFO:    set_io_addr_dec 0 result: ctrl(0x3fff3d01) base(0x0) remap(0x0)"
    "INFO:    Set IO decode window successfully, base(0xc000) win_attr(3d) max_dram_win(2) max_remap(0) win_offset(8)"
