Merge branch 'net-dsa-mv88e6xxx-centralize-SERDES-IRQ-handling' 

Vivien Didelot says:

====================
net: dsa: mv88e6xxx: centralize SERDES IRQ handling

Following Marek's work on the abstraction of the SERDES lanes mapping, this
series trades the .serdes_irq_setup and .serdes_irq_free callbacks for new
.serdes_irq_mapping, .serdes_irq_enable and .serdes_irq_status operations.

This has the benefit to limit the various SERDES implementations to simple
register accesses only; centralize the IRQ handling and mutex locking logic;
as well as reducing boilerplate in the driver.
