In cpu_primary.S
- Assign %rsp in cpu_primary_start_64(), so we can call _relocate()
before any references to the symbols that need to be patched
- Move lidtq instruction and the IDT fixup code after _relocate() call
- In code64 part, replace 'mov' with 'lea' for correct addressing
- No relocation is needed in code32 part
In trampoline.S:
- add trampoline_spinlock_ptr pointer, so we may be able to fixup
trampoline code in HV

- rename 'cpu_set_logical_id()' to 'set_current_cpu_id()'
- rename 'cpu_find_logical_id()' to 'get_cpu_id_from_lapic_id()'
- some clean up in cpu.c & trampolines.s

MISRA C requires that unsigned constants should have the 'U' suffix, while this
C syntax is not accepted by binutils assembler per binutil manual.
This patch explicitly spells out the unsigned constants used in the assembly
files while tracking the original expressions in comments. This fixes build
failure when using binutils <= 2.26.
v2 -> v3:
* Explicitly spell out the unsigned constants in assembly, instead of
duplicating the macros in headers which break the integrity of the
definitions.
v1 -> v2:
* Define different macros instead of wrapping all unsigned constants.
