clocksource/drivers/riscv: Patch riscv_clock_next_event() jump before first use
[ Upstream commit 225b9596cb0227c1c1b1e4a836dad43595c3e61a ]
A static key is used to select between SBI and Sstc timer usage in
riscv_clock_next_event(), but currently the direction is resolved
after cpuhp_setup_state() is called (which sets the next event). The
first event will therefore fall through the sbi_set_timer() path; this
breaks Sstc-only systems. So, apply the jump patching before first
use.
Fixes: 9f7a8ff6391f ("RISC-V: Prefer sstc extension if available")
