Subject: [RFC PATCH 4/4] phy: rockchip-pcie: adjust read mask and write
 strobe disable

Section 17.6.10 of the RK3399 TRM "PCIe PIPE PHY registers Description"
defines asynchronous strobe TEST_WRITE which should be enabled then
disabled and seems to have been copy-pasted as of current. Adjust it.
While at it, adjust read mask which should be the same as write mask.
