riscv: say disabling zicbom if no or bad riscv,cbom-block-size found

Browse source

If Zicbom is present but there was no riscv,cbom-blocks-size property found
during the cpu feeatures probe, or the cbom-block-size is not valid, then
the extension will be disabled. Make the print explicitly say this is
disabled to ensure that there is no confusion about what is being done.
