Introduce generic link section.h symbol files

We create a separate header file for link symbols defined by the link
scripts. It is helpful to have these all in one place and try to
make them common across architectures. Since Linux already has a similar
file, we bring this in even though many of the symbols there are not
relevant to us.

Each architecture has its own asm/sections.h where symbols specifc to
that architecture can be added. For now everything except AVR32 just
includes the generic header.

One change is needed in arch/avr32/lib/board.c to make this conversion
work.

x86: Enable coreboot timestamp facility support in u-boot.

This change turns on the code which allows u-boot to add
timestamps to the timestamp table created by coreboot.

Since u-boot does not use the tsc_t like structure to represent
HW counter readings, this structure is being replaced by 64 bit
integer.

The timestamp_init() function is now initializing the base timer
value used by u-boot to calculate the HW counter increments.

Timestamp facility is initialized as soon as the timestamp table
pointer is found in the coreboot table. The u-boot generated
timer events' ID will start at 1000 to clearly separate u-boot
events from coreboot events in the timer trace.
