cpu/x86/mtrr: Replace CONFIG_CPU_ADDR_BITS with cpu_phys_address_size()
This patch helps to generate correct MTRR mask value while
using set_var_mtrr().
example:
set_var_mtrr(1, 0x99000000, 16*MiB, WP)
without CL :
0x0000000099000005: PHYBASE2: Address = 0x0000000099000000, WP
0x0000000fff000800: PHYMASK2: Length = 0x0000007001000000, Valid
with CL :
0x0000000099000005: PHYBASE1: Address = 0x0000000099000000, WP
0x0000007fff000800: PHYMASK1: Length = 0x0000000001000000, Valid
