Atish Patra	32d0be018f	clocksource/drivers/riscv: Fix clocksource mask ... For all riscv architectures (RV32, RV64 and RV128), the clocksource is a 64 bit incrementing counter. Fix the clock source mask accordingly. Tested on both 64bit and 32 bit virt machine in QEMU.

Atish Patra	26478b2f6a	clocksource/drivers/riscv: Add required checks during clock source init ... Currently, clocksource registration happens for an invalid cpu for non-smp kernels. This lead to kernel panic as cpu hotplug registration will fail for those cpus. Moreover, riscv_hartid_to_cpuid can return errors now. Do not proceed if hartid or cpuid is invalid. Take this opportunity to print appropriate error strings for different failure cases.
