sh: init: use OF_EARLY_FLATTREE for early init
When CONFIG_OF_EARLY_FLATTREE and CONFIG_SH_DEVICE_TREE are not set,
SH3 build fails with a call to early_init_dt_scan(), so in
arch/sh/kernel/setup.c and arch/sh/kernel/head_32.S, use
CONFIG_OF_EARLY_FLATTREE instead of CONFIG_OF_FLATTREE.
Fixes this build error:
../arch/sh/kernel/setup.c: In function 'sh_fdt_init':
../arch/sh/kernel/setup.c:262:26: error: implicit declaration of function 'early_init_dt_scan' [-Werror=implicit-function-declaration]
262 | if (!dt_virt || !early_init_dt_scan(dt_virt)) {
Fixes: 03767daa1387 ("sh: fix build regression with CONFIG_OF && !CONFIG_OF_FLATTREE")
Fixes: eb6b6930a70f ("sh: fix memory corruption of unflattened device tree")
