[PATCH v5 4/4] phy: ti-pipe3: Fix clock leak in init error path

[Hongling Zeng]

When regmap_update_bits() fails in ti_pipe3_init() for PCIe mode,
the function returns the error without calling ti_pipe3_disable_clocks().
This leaves the clocks permanently enabled since the PHY framework won't
invoke the .exit callback on init failure.

Fix this by adding proper clock cleanup in the PCIe error path, consistent
with how the DPLL program error path handles cleanup.
