nb/intel/i945: Remove initialization already done at bootblock
Upper 128bytes of CMOS and RCBA are already enabled at bootblock. Tested on 945g-MA. Resuming from suspend is working fine Change-Id: I3f34380b0e700cf60688ad58465f9cb0aeda0928 Signed-off-by: Elyes HAOUAS <ehaouas@noos.fr> Reviewed-on: https://review.coreboot.org/c/31107 Reviewed-by: Nico Huber <nico.h@gmx.de> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
