[PATCH v2 2/5] target/riscv: Disable "G" by default

From: Tsukasa OI
Subject: [PATCH v2 2/5] target/riscv: Disable "G" by default
Date: Sun, 15 May 2022 11:56:08 +0900

Because "G" virtual extension expands to "IMAFD", we cannot separately
disable extensions like "F" or "D" without disabling "G".  Because all
"IMAFD" are enabled by default, it's harmless to disable "G" by default.
