Subject: [PATCH 5.17 0090/1126] RISC-V: Declare per cpu boot data as static

From: Atish Patra <atishp@...osinc.com>

commit f1de125766d6f377a4b5d5821bc12928f929a4eb upstream.

The per cpu boot data is only used within the cpu_ops_sbi.c. It can
be delcared as static.

Fixes: 9a2451f18663 ("RISC-V: Avoid using per cpu array for ordered booting")
