openrisc: Remove unused tlb_init function

When compiling with W=1 enabling -Wmissing-prototypes the compiler warns: arch/openrisc/mm/tlb.c:188:13: error: no previous prototype for 'tlb_init' [-Werror=missing-prototypes] This function is not implemented or used so remove it. Reported-by: Arnd Bergmann <arnd@arndb.de> Closes: https://lore.kernel.org/linux-kernel/20230810141947.1236730-17-arnd@kernel.org/ Signed-off-by: Stafford Horne <shorne@gmail.com>
