ARM: hw_breakpoint: make boot quieter without CPUID feature registers
Booting on a v6 core without the CPUID feature registers (e.g. 1136) leads to a noisy dmesg complaining about their absence. This patch changes the pr_warning into a pr_warn_once to keep the log quieter. Signed-off-by: Will Deacon <will.deacon@arm.com>
