RISC-V: XTheadMemPair: Remove register restrictions for store-pair
The XTheadMemPair does not define any restrictions for store-pair
instructions (th.sdd or th.swd). However, the current code enforces
the restrictions that are required for load-pair instructions.
Let's fix this by removing this code.
