Using guard notation makes the code more compact and error handling
more robust by ensuring that mutexes are released in all code paths
when control leaves critical section.

Refactor the mutex handling in the rockchip_pcie_phy_power_on() function to
improve code readability and maintainability. The goto statement has
been removed, and the mutex_unlock call is now directly within the
conditional block.
Return the result of reset_control_deassert() or regmap_read_poll_timeout()
function, with 0 indicating success and an error code indicating failure.

PLL status
Replace open-coded phy PCIe reference clk PLL status polling with
regmap_read_poll_timeout API. This change simplifies the code without
altering functionality.

Use devm_clk_get_enabled() instead of devm_clk_get() to make the code
cleaner and avoid calling clk_disable_unprepare(), as this is exactly
what this function does. Use the dev_err_probe() helper to simplify
error handling during probe.

Use the dev_err_probe() helper to simplify error handling during probe.
This also handle scenario, when -EDEFER is returned and useless error
is printed.

The xlate callbacks are supposed to translate of_phandle_args to proper
provider without modifying the of_phandle_args. Make the argument
pointer to const for code safety and readability.

Use preferred device_get_match_data() instead of of_match_device() to
get the driver match data. With this, adjust the includes to explicitly
include the correct headers.

Reconstruct the whole driver to support per-lane PHYs. Note that we could
also support the legacy PHY if you don't provide argument to
rockchip_pcie_phy_of_xlate().
