northbridge/intel/i945: Change types to uintptr_t where appropriate

Prepares compilation for x86_64 by avoiding casts to different sizes.

Current patch fixes:
1.
src/northbridge/intel/i945/raminit.c: In function 'ram_read32':
src/northbridge/intel/i945/raminit.c:77:16: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
   77 |         read32((void *)offset);
      |                ^

2.
src/northbridge/intel/i945/rcven.c: In function 'sample_strobes':
src/northbridge/intel/i945/rcven.c:29:24: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
   29 |                 read32((void *)addr);
      |                        ^
src/northbridge/intel/i945/rcven.c:30:24: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
   30 |                 read32((void *)(addr + 0x80));
      |                        ^
