[PATCH 08/19] hw/net/bcm2838_genet: add GENET register structs, part 4/4

[Marcelo Manzo <marcelomanzo@gmail.com>]

From: Sergey Kambalin <serg.oker@gmail.com>

Add the PHY "shadow" register structs (BCM54213PE PHY-specific
clock control, RGMII mode, LED, and expansion-block registers
accessed via the AUX_CTL/EXP_SHD indirection scheme) used by the
MDIO emulation added in a later patch.

Part of Sergey Kambalin's original Raspberry Pi 4B PCIe/GENET
networking series (patchwork series 829638, posted to qemu-devel in
2024, never merged). Carried forward and completed by Marcelo Manzo.
