[coreboot] [PATCH]Some more removal of c-includes in AMD code

[Patrick Georgi]

Hi,

attached patch removes another set of includes from Fam10 romstages:

northbridge/amd/amdht/ht_wrapper.c
northbridge/amd/amdfam10/raminit_amdmct.c
cpu/amd/model_10xxx/fidvid.c
pc80/mc146818rtc_early.c

are included from within other AMD files now (where they are
references). They can later be replaced with header file includes and
initobj-linking.
