x86/cpu: Clean up intel_tlb_table[]

- Remove the unneeded backslash at EOL: that's not a macro.
  And let's please checkpatch by aligning to open parenthesis.

- For 0x4f descriptor, remove " */" from the info field.

- For 0xc2 descriptor, sync the beginning of info to match the tlb_type.

(The value of info fields could be made more regular, but it's unused by
 the code and will be read only by developers, so don't bother.)
