[PULL v2 01/19] target/riscv: Remove condition guarding register zero for auipc and lui

[Alistair Francis]

From: Víctor Colombo <victor.colo...@eldorado.org.br>

Commit 57c108b8646 introduced gen_set_gpri(), which already contains
a check for if the destination register is 'zero'. The check in auipc
and lui are then redundant. This patch removes those checks.
