[PATCH 1/1] riscv: add NULL check before calling strlen in the riscv cpu's get_desc()

Without the NULL check, if the devicetree that u-boot loads does not have a compatible property then a store access fault will be raised and force the machine to reset, due to the NULL pointer we passed to strlen. This commit adds this check and will return -ENOSPC to indicate the get_desc failed.
