ARM: lpc32xx: Use kmemdup to replace duplicating its implementation
kmemdup is better than kmalloc() + memcpy(), and we do not like open code. So just use kmemdup instead. Signed-off-by: zhong jiang <zhongjiang@huawei.com> [vzapolskiy: resolved a merge conflict] Signed-off-by: Vladimir Zapolskiy <vz@mleia.com>
