lib: Simplify sbi_platform early_init() and final_init() hooks
Instead of having separate early_init() and final_init() hooks for cold and warm boot, this patch updates struct sbi_platform to have just one early_init() and one final_init() hook. The type of boot (cold or warm) is now a boolean flag parameter for the updated early_init() and final_init() hooks. Signed-off-by: Anup Patel <anup.patel@wdc.com>
