soc/intel/common: Configure all possible GFX DSM memory reserve range

Intel internal graphics preallocated memory size should be selected from
below lists as per Intel FSP UPD header:

0x00:0MB, 0x01:32MB, 0x02:64MB, 0x03:96MB, 0x04:128MB, 0x05:160MB,
0xF0:4MB, 0xF1:8MB, 0xF2:12MB, 0xF3:16MB, 0xF4:20MB, 0xF5:24MB,
0xF6:28MB, 0xF7:32MB, 0xF8:36MB, 0xF9:40MB, 0xFA:44MB, 0xFB:48MB,
0xFC:52MB, 0xFD:56MB, 0xFE:60MB

This patch ensures that coreboot can report the same preallocated
memory range for intel grapics during memory layout calculation.

TEST=Set IgdDvmt50PreAlloc UPD with different ranges between 4MB-60MB
and coreboot could able to calculate GFX DSM range accordingly.
