Subject: [PATCH 1/2] video/sis: Use SiS_DRAMType from init.h and annotate it __devinitconst

This patch removes the duplicated SiS_DRAMType from sis_main.c since it
is already defined exactly the same in init.h.
Since SiS_DRAMType is const and only used by sisfb_post_300_rwtest which is
marked __devinit we can also annotate SiS_DRAMType with __devinitconst.

And since hardcoded values are bad we use ARRAY_SIZE for determining the
size of SiS_DRAMType ;)
