Kunihiko Hayashi 8bc305d146 phy: uniphier-pcie: Fix updating phy parameters
[ Upstream commit 4a90bbb478dbf18ecdec9dcf8eb708e319d24264 ]

The current driver uses a value from register TEST_O as the original
value for register TEST_I, though, the value is overwritten by "param",
so there is a bug that the original value isn't no longer used.

The value of TEST_O[7:0] should be masked with "mask", replaced with
"param", and placed in the bitfield TESTI_DAT_MASK as new TEST_I value.
