soc/amd/picasso: Use readelf to find bootblock size and location
The Picasso build describes the DRAM region where the PSP places
our bootblock. Rather than relying on Kconfig values, make the build
more robust by using the actual size and target base address
from the boot block's ELF file.
Sample output of "readelf -l bootblock.elf" is:
------------------
Elf file type is EXEC (Executable file)
Entry point 0x203fff0
There is 1 program header, starting at offset 52
Program Headers:
Type Offset VirtAddr PhysAddr FileSiz MemSiz Flg Align
LOAD 0x001000 0x02030000 0x02030000 0x10000 0x10000 RWE 0x1000
Section to Segment mapping:
Segment Sections...
00 .text .data .bss .reset
------------------
We can extract the information from here.
