* config/tc-riscv.c (enum riscv_csr_class): Add CSR classes for
'Sstc' extension. (riscv_csr_address): Add handling for new CSR
classes.
* testsuite/gas/riscv/csr-dw-regnums.s: Add new CSRs.
* testsuite/gas/riscv/csr-dw-regnums.d: Likewise.
* testsuite/gas/riscv/csr.s: Add new CSRs.
* testsuite/gas/riscv/csr-version-1p9p1.d: Likewise.
* testsuite/gas/riscv/csr-version-1p9p1.l: Likewise.
* testsuite/gas/riscv/csr-version-1p10.d: Likewise.
* testsuite/gas/riscv/csr-version-1p10.l: Likewise.
* testsuite/gas/riscv/csr-version-1p11.d: Likewise.
