[PATCH] phy: ti-pipe3: Do not overwrite the whole PROGRAMMABILITY register

[Rolf Evers-Fischer]

From: Rolf Evers-Fischer <rolf.evers.fischer@xxxxxxxxx>

Previously, ti_pipe3_calibrate() wrote all bits in the
PCIEPHYRX_ANA_PROGRAMMABILITY register, thus overwriting bits,
which should not be modified.
Fix ti_pipe3_calibrate() so that it only modifies LOSD and
INTERFACE bits.
