Zide Chen 9323f811ea HV: Prepare cpu_secondary.S for AP trampoline code relocation
V1->V2: removed CONFIG_LOW_RAM_START and added ".org 0" to
cpu_secondary.S

The assumption is trampoline code is relocated while HV is not, so:

trampoline code is built at address 0, and CS register is updated
by SIPI to reflect the correct vector

in real mode part, added extra pointers for page tables and long jump buffer
so it's possible for HV code to patch the relocation offset

in long mode part, use absolute addressing when referring HV symbols,
and use relative addressing for symbols within trampoline code
