soc/amd/*/Makefile: fix readelf parameters to get bootblock size

This ports forward part of commit df0968062622 ("soc/amd/picasso: Add
support for 64bit builds") to the newer AMD SoCs.

Use -Wl instead of -l to get the output format that the commands in the
Makefile expect to extract the value for PSP_BIOSBIN_SIZE. Without this
change, readelf will split the output into two lines in case of a 64 bit
coreboot build. This results in invalid amdcompress and amdfwtool
command lines which will cause the amdfwtool call to fail with

Error: BIOS binary destination and uncompressed size are required

With the old readelf -l command we get this output in a 64 bit build:

Program Headers:
  Type           Offset             VirtAddr           PhysAddr
                 FileSiz            MemSiz              Flags  Align
  LOAD           0x0000000000000080 0x0000000002030000 0x0000000002030000
                 0x0000000000010000 0x0000000000010000  RWE    0x10

while we get the correct output in a 32 bit build:

Program Headers:
  Type           Offset   VirtAddr   PhysAddr   FileSiz MemSiz  Flg Align
  LOAD           0x000060 0x02030000 0x02030000 0x10000 0x10000 RWE 0x20

With readelf -Wl we also get the expected output in a 64 bit build:

Program Headers:
  Type           Offset   VirtAddr           PhysAddr           FileSiz  MemSiz   Flg Align
  LOAD           0x000080 0x0000000002030000 0x0000000002030000 0x010000 0x010000 RWE 0x10

TEST=This fixes the 64 bit build on Cezanne with some follow-up patches
applied.
