[PATCH 2/2] board: qemu-riscv: enable semihosting

[Kautuk Consul]

To use semihosting on qemu RISCV virt machine, we need the
CONFIG_SPL_FS_LOAD_PAYLOAD_NAME define in qemu-riscv.h.

We also need to enable the following configs in defconfigs:
CONFIG_SEMIHOSTING
CONFIG_SPL_SEMIHOSTING
CONFIG_SEMIHOSTING_SERIAL
CONFIG_SERIAL_PROBE_ALL
