[PATCH] vlynq: Fix a compilation with CONFIG_VLYNQ_DEBUG=y

[tianyaxiong]

From: tianyaxiong <tianyaxiong@xxxxxxxxxx>

  The vlynq_dump_regs() and vlynq_dump_mem() are unused ,so when
CONFIG_VLYNQ_DEBUG=y,a compilation issue occurred.
drivers/vlynq/vlynq.c:82:13: error: ‘vlynq_dump_mem’ defined but not used [-Werror=unused-function]
drivers/vlynq/vlynq.c:68:13: error: ‘vlynq_dump_regs’ defined but not used [-Werror=unused-function]

  we can add __always_unused to fix it.
