Toshiba recently launched new revisions of their serial SLC NAND series.
TC58CVG2S0HRAIJ is a refresh of previous series with minor improvements.
Basic parameters are same so lets add support for this new revision.

Datasheet: https://business.kioxia.com/info/docget.jsp?did=58601&prodName=TC58CVG2S0HRAIJ

Tested under kernel 5.4.7.
