When compiled as PIE, executable can be loaded at any memory address.
Lately, OpenSBI switched to such behavior and spike was not able to load
it anymore. This patch add an additional load_offset parameter for
load_elf(). This load_offset value is passed as DRAM_BASE and used only
for ET_DYN elfs.

the default target endian is always little endian:
- mmu::is_target_big_endian() return false
- sim_t::get_target_endianness() return memif_endianness_little
when RISCV_ENABLE_DUAL_ENDIAN macro is undefined

* reduce sig_len constraint to 4 bytes
Spike currently asserts that the signature length should always be a multiple of 16-bytes. However, the compliance suite has agreed to upon the signature being a multiple ot 4-bytes. This prevents some of the tests to run on spike since it fails the assertion.
The proposed change fixes this issue and reduces the assertion to 4 bytes.
* Added size argument to htif arguments and zero padding for signature output. Defaultline size-16.
* Modified type of line_size to unsigned.
* Renamed size to granularity.
* Rename granularity to signature-granularity.

* Adding symbol lookup when --enable-commitlog is enabled
* Removed the #ifdef RISCV_ENABLE_COMMITLOG for all get_symbol related function
Only retained the in processor.cc where it is called.

Firmware implementations, such as OpenSBI's fw_jump, make use of this
feature on other targets to avoid having to be rebuilt every time the
payload is updated.
