Series riscv: Add KGDB and KDB support | expand

Due to lack of hardware breakpoint support, the kernel option
CONFIG_STRICT_KERNEL_RWX should be disabled when using KGDB. However,
CONFIG_STRICT_KERNEL_RWX is always enabled now. Therefore, select
ARCH_OPTIONAL_KERNEL_RWX to enable the Kconfig prompt of
CONFIG_STRICT_KERNEL_RWX so that user can turn it off.
