x86: fix build warnings in real mode code  
  
This recent patch

x86 boot: proper use of ARRAY_SIZE instead of repeated E820MAX constant  
  
caused these new warnings during a normal build:  
  
In file included from linux-2.6/arch/x86/boot/memory.c:17:  
linux-2.6/include/linux/log2.h: In function '__ilog2_u32':  
linux-2.6/include/linux/log2.h:34: warning: implicit declaration of function 'fls'  
linux-2.6/include/linux/log2.h: In function '__ilog2_u64':  
linux-2.6/include/linux/log2.h:42: warning: implicit declaration of function 'fls64'  
linux-2.6/include/linux/log2.h: In function '__roundup_pow_of_two ':  
linux-2.6/include/linux/log2.h:63: warning: implicit declaration of function 'fls_long'  
  
I tried to fix them in log2.h, but it's difficult because the real mode  
environment is completely different from a normal kernel environment. Instead  
define an own ARRAY_SIZE macro in boot.h, similar to the other private  
macros there.
