Use board_early_init_f() instead of mach_cpu_init() for board, the board_early_init_f() is used for board init and after dm_initf, while the mach_cpu_init() is used for CPU/SOC and before dm_initf()(not able to use syscon API). Fixes:9cec336708("rockchip: evb-rv1108: Use syscon API to get grf base") Fixes:4aa33690fc{"rockchip: elgin-rv1108: Use syscon API to get grf base") Signed-off-by: Kever Yang <kever.yang@rock-chips.com>
