ARM: imx8m: Fix reset in SPL on NXP iMX8MP EVK
Board files should not re-implement do_reset() to work around this function not being defined in for specific configurations. Rather, the fix is to compile in drivers which implement this properly. This patch enables sysreset and watchdog drivers in SPL and ties them together to implement the same as the do_reset() hack in the board file, except correctly in the DM/DT framework.
