include: Make sbi_current_hartid() as macro in riscv_asm.h
The sbi_current_hartid() being a regular function is quite expensive because for callers it is a function call instead of a direct CSR read. This patch converts sbi_current_hartid() into a macro in riscv_asm.h. Signed-off-by: Anup Patel <anup.patel@wdc.com> Reviewed-by: Atish Patra <atish.patra@wdc.com>
