[PATCH v2 0/8] mips: econet: Add clk/reset and PCIe support

[Caleb James DeLisle]

Add clock/reset and PCIe support to EcoNet EN751221 and related SoCs.
This builds on the Airoha EN7523 clock driver and the Mediatek PCIe driver.

Patch 6 is upstreaming of Ahmed Naseef's work on EcoNet PCIe, which was
developed to support the EN7528, but which works equally on the EN751221.

There is also a workaround in patch 7 to gracefully handle PCI hardware
which does not advertize a bridge window and instead always reads zero.

Changes in v2:
* clock/econet,en751221-scu.h drop EN751221_MAX_CLKS
* clk-en7523.c add EN751221_MAX_CLKS
* econet,en751221-chip-scu.yaml drop in favor of using mtd/syscon.yaml
* airoha,en7523-scu.yaml drop redundant example
* econet,en751221-pcie-phy.yaml Refer to PHYs as "gen1" and "gen2"
* pcie-mediatek.c Exclude pcie_retrain_link() when building as a module
* en751221.dtsi "econet,en751221-scu" is not a "syscon"
* Rebase to linux-next
* v1: https://lore.kernel.org/linux-mips/20260303190948.694783-1-cjd@cjdns.fr/
