Simplify the interrupt resource lookup code in cpsw_probe() by the
following:
* Only look at the first member of the resource. As the driver only
works for DT-enabled platforms anyway, a resource of type
IORESOURCE_IRQ will only contain one single entry
(res->start == res->end), so there is no need for the iteration.
* Add a bounds check to avoid overflows if we are passed more than
ARRAY_SIZE(priv->irqs_table) resources.
* Assign 'ret' with the return value of devm_request_irq() so that
cpsw_probe() returns the appropriate error code.
* If devm_request_irq() fails, report the error code in the log
message.

In commit 629c9a8fd0 (drivers: net: cpsw: Add
default vlan for dual emac case also), api cpsw_add_default_vlan() also
changes the port vlan which is required to seperate the ports which results
in the following behavior
In Dual EMAC mode, when both the Etnernet connected is connected to same
switch, it creates a loop in the switch and when a broadcast packet is
received it is forwarded to the other port which stalls the whole switch
and needs a reset/power cycle to the switch to recover. So intead of using
the api, add only the default VLAN entry in dual EMAC case.
