phy: qcom: qmp-pcie: Add Nord Gen5x16 PCIe multi-PHY support

This commit adds support for the Nord Gen5x16 bifurcated QMP PCIe PHY. It
adds configurations for x16, x8+x8, x8+x4+x4, and x8+x4+x2+x2 lane modes,
along with register programming and power sequencing.

[Severity: Low]
Does this code accidentally pass pciephy_port_a_nocsr_reset_l instead of
nord_pciephy_port_a_nocsr_reset_l into the NORD_QMP_PCIE_PORT_CFG macro for
port a (and similarly for port b)?

This leaves the newly defined nord_pciephy_port_a_nocsr_reset_l and
nord_pciephy_port_b_nocsr_reset_l static arrays entirely unused.

This will trigger a -Wunused-variable compiler warning, which can cause
build failures when compiling the kernel with -Werror.
