rde: optimize debug regs clear logic

driver inclusion
category: bugfix
bugzilla: NA
CVE: NA

In this patch, we try to optimize debug regs clear logic.
We add hisi_rde_debug_regs_clear interface and this interface
will be called only in probe and remove, which can keep value
of debug regs.
Otherwise, we optimize print interface of hpre_probe and add
qp_num print of hisi_qm_create_qp_nolock.
