[PATCH] RISC-V: move riscv_cbom_block_size to the correct #ifdef block

[Heiko Stuebner]

riscv_cbom_block_size is used by all current non-coherent dma operations,
not only the zicbom variant. So move it over the block also containing
the riscv_noncoherent_supported() prototype.

Fixes: 8f7e001e0325 ("RISC-V: Clean up the Zicbom block size probing")
