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.
