commit 20f14714169 ("imx: spl: Update NAND bootmode detection bit") broke the NAND bootmode detection by checking if BOOT_CFG1[7:4] == 0x8 for NAND boot mode. This commit essentially reverts it, while using the IMX6_BMODE_* macros that were introduced since.
Tables 8-7 & 8-10 from IMX6DQRM say the NAND boot mode selection is done when BOOT_CFG1[7] is 1, but BOOT_CFG1[6:4] is not necessarily 0x0 in this case. Actually, NAND boot mode is when 0x8 <= BOOT_CFG1[7:4] <= 0xf, like it was in the code before.
