phy: qcom: qmp-pcie: Add X1P42100 Gen4x4 PHY

Add a new, common configuration for Gen4x4 V6 PHYs without an init
sequence.

The bootloader configures the hardware once and the OS retains that
configuration by using the NOCSR reset line (which doesn't drop
register state on assert) in place of the "full reset" one.

Use this new configuration for X1P42100's Gen4x4 PHY.
