[PATCH v4 0/4] x86/tdx: Clean up the definitions of TDX TD ATTRIBUTES

[Xiaoyao Li]

The main purpose of this series was to remove redundant macros between
core TDX and KVM, along with a typo fix. They were implemented as patch 1
and patch 2.

During the review of v1 and v2, there was encouragement to refine the
names of the macros related to TD attributes to clarify their scope.
Thus patch 3 and patch 4 are added.

Note, Binbin suggested to rename tdx_attributes[] to tdx_td_attributes[]
during v3 review. However, this v4 doesn't do it but leaves it for future
cleanup to avoid making it more complicated because it also looks like
it needs to rename "Attributes" to "TD Attributes" in tdx_dump_attributes(),
which has user visibility change.

[PATCH v4 1/4] x86/tdx: Fix the typo in TDX_ATTR_MIGRTABLE

[Xiaoyao Li]

The TD scoped TDCS attributes are defined by bit positions. In the guest
side of the TDX code, the 'tdx_attributes' string array holds pretty
print names for these attributes, which are generated via macros and
defines. Today these pretty print names are only used to print the
attribute names to dmesg.

Unfortunately there is a typo in the define for the migratable bit.
Change the defines TDX_ATTR_MIGRTABLE* to TDX_ATTR_MIGRATABLE*. Update
the sole user, the tdx_attributes array, to use the fixed name.

Since these defines control the string printed to dmesg, the change is
user visible. But the risk of breakage is almost zero since it is not
exposed in any interface expected to be consumed programmatically.

[PATCH v4 3/4] x86/tdx: Rename TDX_ATTR_* to TDX_TD_ATTR_*

[Xiaoyao Li]

The macros TDX_ATTR_* and DEF_TDX_ATTR_* are related to TD attributes,
which are TD-scope attributes. Naming them as TDX_ATTR_* can be somewhat
confusing and might mislead people into thinking they are TDX global
things.

Rename TDX_ATTR_* to TDX_TD_ATTR_* to explicitly clarify they are
TD-scope things.
