lib: Emulate HTIMEDELTA CSR for platforms not having TIME CSR
For platforms not having TIME CSR, we trap-n-emulate TIME CSR read/write in OpenSBI. Same rationale applies to HTIMEDELTA CSR as well so we trap-n-emulate HTIMEDELTA CSR for platforms not having TIME CSR. Signed-off-by: Anup Patel <anup.patel@wdc.com>
