cpuidle, tdx: Make TDX code noinstr clean
objtool found a few cases where this code called out into instrumented
code:
vmlinux.o: warning: objtool: __halt+0x2c: call to hcall_func.constprop.0() leaves .noinstr.text section
vmlinux.o: warning: objtool: __halt+0x3f: call to __tdx_hypercall() leaves .noinstr.text section
vmlinux.o: warning: objtool: __tdx_hypercall+0x66: call to __tdx_hypercall_failed() leaves .noinstr.text section
Fix it by:
- moving TDX tdcall assembly methods into .noinstr.text (they are already noistr-clean)
- marking __tdx_hypercall_failed() as 'noinstr'
- annotating hcall_func() as __always_inline
