Use the proper accessors instead of open access to irq_desc.

Interrupt controllers' hooks are executed in the atomic context, so
they are not permitted to sleep (with RT kernels non-raw spinlocks are
sleepable). So, socrates_fpga_pic_lock has to be a real (non-sleepable)
spinlock.

Now we use printf style alignment there is no need to manually space
these fields.

Writing a driver using SCLPC on the MPC5200B I detected, that the
intspec arrays to map irqs to Linux virq cannot be const, because the
mapping and xlate functions only take non const pointers. All those
functions do not modify the intspec, so a const pointer could be used.

The typename member of struct irq_chip was kept for migration purposes
and is obsolete since more than 2 years. Fix up the leftovers.

get_irq_desc() is a powerpc-specific version of irq_to_desc(). That
is reason enough to remove it, but it also doesn't know about sparse
irq_desc support which irq_to_desc() does (when we enable it).

Supported are Ethernet, serial console, I2C, I2C-based RTC and
temperature sensors, NOR and NAND flash, PCI, USB, CAN and Lime
display controller.

The multiplexing of FPGA interrupts onto PowerPC interrupt lines is
supported through our own fpga_pic interrupt controller driver.

For example the SJA1000 controller is level low sensitive connected to
fpga_pic line 2 and is routed to the second (of three) irq lines to
the CPU:

    can@3,100 {
            compatible = "philips,sja1000";
            reg = <3 0x100 0x80>;
            interrupts = <2 2>;
            interrupts = <2 8 1>;   // number, type, routing
            interrupt-parent = <&fpga_pic>;
    };
