[PATCH 1/3] riscv: Add timer_get_us() for tracing

timer_get_us() will use timer_ops->get_count() function for timer counter. For S-mode U-Boot, CSR_TIMEH and CSR_TIME will provide a timer counter and For M-mode U-Boot, mtime register will provide the same. Signed-off-by: Pragnesh Patel --- arch/riscv/lib/Makefile | 1 + arch/riscv/lib/timer.c
