opensbi: Use -ffreestanding compiler options
This usually helps compiler to not use built-in optimizations
for string functions and mem* functions unnecessarily, since OE's
compiler is hosted for linux cross compile, this also means we instruct
it rightly for building a baremetal application
Refresh the patches to apply without fuzz
Fixes linking errors e.g.
platform/qemu/virt/lib/libplatsbi.a(sbi_string.o): in function `sbi_memset':
| /mnt/b/yoe/build/tmp/work/riscv64-yoe-linux/opensbi/0.5-r0/git/lib/sbi/sbi_string.c:102: undefined reference to `memset'
| collect2: error: ld returned 1 exit status
