====================
Add AM335x PG1.0 CPSW errata workaround

With commit fe5774054a19 ("drivers: net: cpsw: remove
disable_irq/enable_irq as irq can be masked from cpsw itself"),
CPSW on AM335x beagle bone white is broken as there is a errata
for AM335x PG1.0. This patch series implements the workaround by
disabling the interrupts from ARM IRQ controller for AM335x SoC
in addition to the masking of interrupts in CPSW.
