This patch fixes the following Ecc reported error: Variable name does not follow the rules: 1. First character should be upper case 2. Must contain lower case characters 3. No white space characters 4. Global variable name must start with a 'g' Indeed, according to the EDK II C Coding Standards Specification, s5.6.2.2 "Enumerated Types" and s4.3.4 Function and Data Names, elements of an enumerated type shoud be a mixed upper- and lower-case text. A max element is also added, as advised by s5.6.2.2.3 of the same document.
