fix(data): All "upper half" CSRs are RV32-only (#791)

ThinkOpenly · web-flow · commit 95013b434fff · 2025-05-21T15:03:58.000Z
Most "upper half" CSRs are already defined "base: 32"...
except "htimedeltah" and "minstreth". Fix them.

BREAKING CHANGE: Some "upper half" CSRs no longer available to RV64.

CSRs "htimedeltah" and "minstreth" were mistakenly available to RV64.
They will no longer be available to RV64.
