Log: Fix definition of SSTATUS_SD The SD bit is defined as the MSB of the sstatus register, meaning its position will vary depending on the CSR's length. Previously, there were two (unused) defines for this, for the 32 and 64-bit cases, but their definitions were swapped. Consolidate these into one define: SSTATUS_SD, and make the definition dependent on the value of __riscv_xlen.
