This adds correct interrupt routing settings for IRQs on the RTL839x SoCs.
It also speeds up irq handling based on work by biot for all SoCs.

Do some minor empty lines cleanup, i.e. remove those at EOF and
add some for cosmetic reasons/consistency.

This adds support for the RTL838x Architecture.
SoCs of this type are used in managed and un-managed Switches and Routers
with 8-28 ports. Drivers are provided for SoC initialization, GPIOs, Flash,
Ethernet including a DSA switch driver and internal and external PHYs used
with these switches.
Supported SoCs:
RTL8380M
RTL8381M
RTL8382M
The kernel will also boot on the following RTL839x SoCs, however driver
support apart from spi-nor is missing:
RTL8390
RTL8391
RTL8393
The following PHYs are supported:
RTL8214FC (Quad QSGMII multiplexing GMAC and SFP port)
RTL8218B internal: internal PHY of the RTL838x chips
RTL8318b external (QSGMII 8-port GMAC phy)
RTL8382M SerDes for 2 SFP ports
Initialization sequences for the PHYs are provided in the form of
firmware files.
Flash driver supports 3 / 4 byte access
DSA switch driver supports VLANs, port isolation, STP and port mirroring.
The ALLNET ALL-SG8208M is supported as Proof of Concept:
RTL8382M SoC
1 MIPS 4KEc core @ 500MHz
8 Internal PHYs (RTL8218B)
128MB DRAM (Nanya NT5TU128MB)
16MB NOR Flash (MXIC 25L128)
8 GBEthernet ports with one green status LED each (SoC controlled)
1 Power LED (not configurable)
1 SYS LED (configurable)
1 On-Off switch (not configurable)
1 Reset button at the right behind right air-vent (not configurable)
1 Reset button on front panel (configurable)
12V 1A barrel connector
1 serial header with populated standard pin connector and with markings
GND TX RX Vcc(3.3V), connection properties: 115200 8N1
To install, upload the sysupgrade image to the OEM webpage.
