Merge patch series "Some style cleanups for recent extension additions"

Heiko Stuebner <heiko@sntech.de> says:

As noted by some people, some parts of the recently added extensions
(svpbmt, zicbom) + t-head errata could use some styling upgrades.

So this series provides these.

changes in v2:
- add patch also converting cpufeature probe to BIT()
- update commit message in patch1 (Conor)

Heiko Stuebner (5):
  riscv: cleanup svpbmt cpufeature probing
  riscv: drop some idefs from CMO initialization
  riscv: use BIT() macros in t-head errata init
  riscv: use BIT() marco for cpufeature probing
  riscv: check for kernel config option in t-head memory types errata
