hw/riscv: Add optional symbol callback ptr to riscv_load_firmware()

Browse source 
This patch adds an optional function pointer, "sym_cb", to
riscv_load_firmware() which provides the possibility to access
the symbol table during kernel loading.

The pointer is ignored, if supplied with flat (non-elf) firmware image.

The Spike board requires it locate the HTIF symbols from firmware ELF
passed via "-bios" option.
