clocksource: new RISC-V SBI timer driver
The RISC-V ISA defines a per-hart real-time clock and timer, which is
present on all systems. The clock is accessed via the 'rdtime'
pseudo-instruction (which reads a CSR), and the timer is set via an SBI
call.
Contains various improvements from Atish Patra <atish.patra@wdc.com>.
