powerpc: remove checks for binutils older than 2.25 (2023-06-27 16:59:29 +1000)

- ------------------------------------------------------------------
powerpc updates for 6.5

- Extend KCSAN support to 32-bit and BookE. Add some KCSAN annotations.

- Make ELFv2 ABI the default for 64-bit big-endian kernel builds, and use
the -mprofile-kernel option (kernel specific ftrace ABI) for big endian
ELFv2 kernels.

- Add initial Dynamic Execution Control Register (DEXCR) support, and allow
the ROP protection instructions to be used on Power 10.

- Various other small features and fixes.
