s32g SoC family includes 2 serdes subsystems which are made of one PCIe

configured to output PCIe lanes and/or SGMII.
    
Implement PCIe phy and XPCS support.

- Fix compile_test
- Use devm_reset_control_get_exclusive()
- Fix s32g_serdes_phy_set_mode_ext()

Hi Vincent, all,
I'm taking over the S32G SerDes/XPCS upstreaming. The effort has moved in-house
at NXP and I'll be carrying it forward, continuing from this v2 rather than
restarting from zero.

Vincent, thanks for the v1->v2 groundwork. I'll keep your authorship on the
patches that originate from your series (Co-developed-by plus your
Signed-off-by) and build on top; I'll send you v3 off-list first, as you
offered.

A v3 is in preparation and will come as an RFC, with the v2 review comments
addressed.

Vincent, if you're OK with the handoff, a short ack here would help make the
transition visible to the reviewers.

Thanks.
