ENGR00155279: Change ESDCTL_0x82228080 to ESDCTL_0x82226080 for mx35
In mx35, when testing TVIN, the screen will flick. We find that flickers will get better when using ESDCTL_0x82226080 against ESDCTL_0x82228080 for register SCDCTL0. The origin value ESDCTL_0x82228080 in lowlevel_init.S will be called in external boot which will reduce the bandwidth. Signed-off-by: Terry Lv <r65388@freescale.com>
