Subject: [PATCH] feat: add dsi boot blobs cut from the dsi nands

Each blob is TWLCFG 0x88-0x1AF, HWINFO_N 0x88-0x9B and HWINFO_S 0x88-0x9F, read from a retail NAND dump by DSperate's own nand_boot_blobs at ddf2910e. The primary comes from dsi_nand.bin, the seven others from the regional dumps and the dsi_nand.bin variant.
