Subject: [PATCH] IB/hns: include linux/of.h to fix build failure

I see the following build error in an arm64 randconfig build:

drivers/infiniband/hw/hns/hns_roce_hw_v1.c: In function 'hns_roce_v1_reset':
drivers/infiniband/hw/hns/hns_roce_hw_v1.c:1384:15: error: implicit declaration of function 'of_parse_phandle' [-Werror=implicit-function-declaration]

Fix this by including linux/of.h directly.
