Dennis Chen c75343972b efi/arm: Fix the format of EFI debug messages 
When both EFI and memblock debugging is enabled on the kernel command line:

  'efi=debug memblock=debug'

.. the debug messages for early_con look the following way:

 [    0.000000] efi:   0x0000e1050000-0x0000e105ffff [Memory Mapped I/O  |RUN|  |  |  |  |  |  |   |  |  |  |UC]
 [    0.000000] efi:   0x0000e1300000-0x0000e1300fff [Memory Mapped I/O  |RUN|  |  |  |  |  |  |   |  |  |  |UC]
 [    0.000000] efi:   0x0000e8200000-0x0000e827ffff [Memory Mapped I/O  |RUN|  |  |  |  |  |  |   |  |  |  |UC]
 [    0.000000] efi:   0x008000000000-0x008001e7ffff [Runtime Data       |RUN|  |  |  |  |  |  |   |WB|WT|WC|UC]
 [    0.000000] memblock_add: [0x00008000000000-0x00008001e7ffff] flags 0x0 early_init_dt_add_memory_arch+0x54/0x5c
 [    0.000000] *
 ...

Note the misplaced '*' line, which happened because the memblock debug message
was printed while the EFI debug message was still being constructed..

This patch fixes the output to be the expected:

 [    0.000000] efi:   0x0000e1050000-0x0000e105ffff [Memory Mapped I/O  |RUN|  |  |  |  |  |  |   |  |  |  |UC]
 [    0.000000] efi:   0x0000e1300000-0x0000e1300fff [Memory Mapped I/O  |RUN|  |  |  |  |  |  |   |  |  |  |UC]
 [    0.000000] efi:   0x0000e8200000-0x0000e827ffff [Memory Mapped I/O  |RUN|  |  |  |  |  |  |   |  |  |  |UC]
 [    0.000000] efi:   0x008000000000-0x008001e7ffff [Runtime Data       |RUN|  |  |  |  |  |  |   |WB|WT|WC|UC]*
 [    0.000000] memblock_add: [0x00008000000000-0x00008001e7ffff] flags 0x0 early_init_dt_add_memory_arch+0x54/0x5c
 ...

Note how the '*' is now in the proper EFI debug message line.
