[PATCH v6 2/4] clocksource/drivers: Add CLINT timer driver

We add a separate CLINT timer driver for Linux RISC-V M-mode (i.e. RISC-V NoMMU kernel). The CLINT MMIO device provides three things: 1. 64bit free running counter register 2. 64bit per-CPU time compare registers 3. 32bit per-CPU inter-processor interrupt registers Unlike other timer devices,
