cpu: imx8: fix type and rate detection
CPU type and rate detection is broken, for A35 cpu we get A53: ... sc_pm_get_clock_rate: resource:0 clk:2: res:3 Could not read CPU frequency: -22 CPU: NXP i.MX8QXP RevB A53 at 0 MHz at 47C Fixes: 55bc96f3b675 ("cpu: imx8: fix get core name and rate") Signed-off-by: Anatolij Gustschin <agust@denx.de> Reviewed-by: Peng Fan <peng.fan@nxp.com>
