[RK3399][Android6.0] 系統重新開機支援恢複出廠設定參數

Platform: Rockchip

OS: Android 6.0

Kernel: 3.10.92

reboot的boot flag請看文章　 [RK3399][Android6.0] 系統支援的重新開機模式　

注意到boot mode table中有對wipe data的支援(BOOT_WIPEDATA)

enum {
    BOOT_NORMAL = 0, /* normal boot */
    BOOT_LOADER,     /* enter loader rockusb mode */
    BOOT_MASKROM,    /* enter maskrom rockusb mode (not support now) */
    BOOT_RECOVER,    /* enter recover */
    BOOT_NORECOVER,  /* do not enter recover */
    BOOT_SECONDOS,   /* boot second OS (not support now)*/
    BOOT_WIPEDATA,   /* enter recover and wipe data. */
    BOOT_WIPEALL,    /* enter recover and wipe all data. */
    BOOT_CHECKIMG,   /* check firmware img with backup part(in loader mode)*/
    BOOT_FASTBOOT,   /* enter fast boot mode */
    BOOT_SECUREBOOT_DISABLE,
    BOOT_CHARGING,   /* enter charge mode */
    BOOT_MAX         /* MAX VALID BOOT TYPE.*/
};           

rk對這個沒有做全，隻在uboot中(board_fbt_get_reboot_type())判斷有沒有wipe data的boot flag,　而在kernel中沒有去記錄儲存下來．

下面是添加的改動，修改後就可以支援如下指令直接恢複出廠設定了．

這樣比文章　[RK3288][Android6.0] 調試筆記 — 指令行恢複出廠設定　的方式少執行一步了．
