[PATCH v2 2/3] target/riscv: Make CPU property names lowercase

[Tsukasa OI]

Many CPU properties for RISC-V are in lowercase except those with
"capitalized" (or CamelCase) names:

-   Counters
-   Zifencei
-   Zicsr
-   Zfh
-   Zfhmin
-   Zve32f
-   Zve64f

This commit makes lowercase names primary but keeps capitalized names
as aliases (for backward comatibility, but with deprecated status).
