Subject: [PATCH 5.13 078/127] r8152: fix writing USB_BP2_EN

From: Hayes Wang <hayeswang@...ltek.com>

[ Upstream commit a876a33d2a1102f99fc782fefb784f4dd4841d8c ]

The register of USB_BP2_EN is 16 bits, so we should use
ocp_write_word(), not ocp_write_byte().

Fixes: 9370f2d05a2a ("support request_firmware for RTL8153")
