sdvx: prevent the game from trying a random ASIO driver (#488)

## Link to GitHub Issue, if one exists
n/a

## Description of change
SDVX EG final started to pick an ASIO driver at random and tries to open
it, which causes crashes / hangs if the driver is not compatible
(ASIO4ALL in particular)

Only allow the game to access `HKLM\SOFTWARE\ASIO` if the user has a
Xonar AE, or if ASIO was configured using -sdvxasio.

## Testing
Tested year 1 data and EG final.

 ### Code style requirements
 * Indents are four spaces.
+* Try to keep under 100 characters per line. This includes comments and string literals.
+* Avoid making unnecessary formatting or whitespace changes in a PR; e.g., watch out for text editor automatically stripping trailing whitespace. It pollutes the diff and slows down code review.
 * Always use \{ curly braces \} when appropriate; do not omit them even when it's optional; such as `for` `if` `else`, etc.
