firmware: Move memcpy/memset mapping to fw_base.S
Some of the external firmwares using OpenSBI as library are facing
issues with the weak memcpy() and memset() aliases in libsbi.a so
we move these to fw_base.S. This way mapping of implicit memcpy()
or memset() calls to sbi_memcpy() or sbi_memset() will only be done
for OpenSBI firmwares.
(Refer, https://github.com/riscv-software-src/opensbi/issues/234)
In addition, we also add memmove() and memcmp() mappings in fw_base.S
because as-per the GCC documentation the freestanding environment must
provide memcpy(), memmove(), memset(), and memcmp().
