x86: Declare global_data pointer when it is used

Several files use the global_data pointer without declaring it. This works
because the declaration is currently a NOP. But still it is better to
fix this so that x86 lines up with other archs.

x86: Implement panic output for coreboot

panic_puts() can be called in early boot to display a message. It might

x86: Rationalise kernel booting logic and bootstage

The 'Starting linux' message appears twice in the code, but both call

x86: Add TSC timer

This timer runs at a rate that can be calculated, well over 100MHz. It is
ideal for accurate timing and does not need interrupt servicing.

Tidy up some old broken and unneeded implementations at the same time.

To provide a consistent view of boot time, we use the same time
base as coreboot. Use the base timestamp supplied by coreboot
as U-Boot's base time.

While we don't want PCAT timers for timing, we want timer 2 so that we can

bootstage: Add stubs for new bootstage functions

Some functions don't have a stub for when CONFIG_BOOTSTAGE is not defined.
Add one to avoid #ifdefs in the code when this is used in U-Boot.

bootstage: Copy bootstage strings post-relocation

Any pointers to name strings that were passed to bootstage_mark_name()
pre-relocation should be copied post-relocation so that they don't get
trashed as the original location of U-Boot is re-used for other
purposes.

This change introduces a new API call that should be called from
board_init_r() after malloc has been initted on any board that uses
bootstage.
