CDROM: Rename Reset+Init commands approperly, fix "This is Football 2" lockup (#205)

Upon the reset command being issued, we need to set the Mode to 0x20
(as it was confirmed in Mednafen) and also disable the muting.

We also change the seektime for the reset command appropriately.
Please see Mednafen's implementation as reference :
https://github.com/libretro-mirrors/mednafen-git/blob/1899500078169e787f86eb5302a3f35abdaa8764/src/psx/cdc.cpp#L2007

This fixes the black screen issue in "This is Football 2".
This also fixes the black screen issue in Pooh's Party.
