Commit Message

From: Andy Yan <[e-mail]>

Add compatible for the HDPTX PHY on rk3576, which is compatible with
rk3588, but without rst_phy/rst_ropll/rst_lcpll.

In fact, these three reset lines are also optional on the rk3588,
they just used for debug, then they were removed on the rk3576 IC
design.
