[x86 setup] Make struct ist_info cross-architecture, and use in setup code
Make "struct ist_info" valid on both i386 and x86-64, and use the structure by name in the setup code. Additionally, "Intel SpeedStep IST" is redundant, refer to it as IST consistently. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
